- Through June, July, and August, San Francisco has cooler temperatures than any other major U.S. city. And just inland, summer daily high temperatures in the 90s F (above 32°C) are the norm. What factors create such bizarre weather in San Francisco?

You are, hands down, my new favorite channel and I deeply hope the algorithm leads more people to your content! Also, the map at 6:12 is super interesting and would make for a really cool episode in itself on days if you are looking for content ideas.
Thanks, that means a lot! And yeah, there are some great explanations for those interesting patterns. I had thought about discussing that topic and titling it "Geography of Summer in the USA" or something similar.
@@casualearth9076 would love a video on this
I have now added a video about that map, if anyone is interested.
@@casualearth9076
That was a cool video. A good companion to that guy, the windmill logo? The geography guy? He made a video that says why everything west of that one longitude is dead and brown, and everything east is green and vibrant, and why it's a due norg/south line
“The coldest winter I ever spent was summer in San Francisco”-Mark Twain.
Bay Area Native btw
😂😂😂 I love this comment so much
@@southwesthardypalms awesomeness!😂
@@southwesthardypalms lots of spectacular sea life going on out here right now because of these massive anchovy swarms,which is a result of the upwelling that the video was explaining~saw some big pelagic porpoises from the shore on Saturday just incredible
I heard my grandpa say that once and thought he made it up till I was like 30 😭😂
I'm a native San Franciscan and I LOVE the fog!! It keeps it cool and fresh (SO crucial during the summer when the rest of the country is WAY too hot), it's often really beautiful as it rolls through The City, and it has always felt like a very chill, familiar, comforting, and calming blanket to me. Being surrounded and shrouded by low fog gives me a sense of privacy and refuge in this dense city as it tucks me away in its cool cloak. 🌫😌🧡🖤
Isabel Allende could have used your description for her book "Ripper" set in San Francisco
I am an Indian... What other cities in the US are as cool or nearly cool as SF during Summers?
That's one of the most beautiful comments in youtube history.... you should be a songwriter.😊
As a Texan, I was in SF one August. It was wonderful. I left an oven in Austin and had to get a sweater and hoodie when I was in the bay area. Every summer at home, I think of that trip.
I love visiting SF in the summer to escape the Texas infernal heat 😂
Yup, i was there in August. Sunny and 68ish every day. Heaven.
@@mrpartsAhaha i lived 5 years in Austin, the greatest thing was the super high blue skies but the oven weather was relentless and heat wave every summer unpleasant summers which last a 5 months. I now live on the East coast where nature is green and forest means dark shades and big hardwood trees. Here summers are less hot but more humid and skies aren't as beautifully blue but fall and winter have a real flavor to them and Spring is beautiful.
I used to go to Austin in August for a work conference. I soon understood why the conference was always in August. That Austin heat. My employer probably got hotel rooms and stuff for dirt cheap for that time. :)
True but the whole Bay Isn’t like that….All you have to do is cross Bay Bridge and it gets warmer….Or go to the South Bay…San Jose,Palo Alto etc. It gets VERY HOT 80s and up
San Diego County has quite a drastic temperature swing as well. For example, today the temperature is 75F at the coast and 105F in the deserts, only a 50-mile difference. And when I went to school at UC San Diego, my dorm would be cloudy, but my classroom would be in the hot sun. Even though it was just a 10-minute walk away.
This explains why when I visited San Francisco I was blown away how similar the climate is to costal northern Portugal (where I come from).
Porto in the summer can get thick fog in the morning and be 5 to 10c cooler than just 20km inland.
Could you make a video explaining why California has such a similar climate profile as the Iberian peninsula?
Yep, it would be an almost exact parallel.
California has a mostly Mediterranean climate
@@casualearth9076 No, not quite. Santa Cruz is the same latitude as The Algarve. The northernmost border of Portugal with Galicia is the same latitude as the Oregon-California border. O Porto's latitude is as northerly as Humboldt County. San Francisco's latitude is further south a bit than Lisbon's.
@@ldfreitas9437 I meant the physical phenomenon is a parallel, not the latitude.
I have wanted to visit the Azores and the Madeira islands, but I also have wanted to visit southern Europe to see similarities with our climate here in California. Did notice that we have similar climate patterns and environments. Especially Portugal.
Yep. Everyone in the Bay Area tries to warn people about this, no one listens. I cycled across the Golden Gate Bridge almost every day for years, and during the summer it was usually in the mid-to-low 50s with blinding fog blowing across it at 15-20 mph, and yet you'd see endless groups of tourists on rental bikes freezing and miserable in their t-shirts, shorts and flip-flops.
It can be pretty extreme, too. I once went to Fourth of July party a block from Ocean Beach, and the temperature never even cracked 50 degrees. Another time I decided to go mountain biking in San Rafael, which is only 20 miles from the city. It was 63 when I left my house and 96 when I arrived in San Rafael.
As someone from San Rafael, the option of visiting the city (or just like Pt. Reyes, or even just Sausolito) on a hot day is always such a relief
Most cities inland get extremely hot….San Jose,East Bay, even San Mateo county towards San Jose like Palo Alto,Redwood city,San mateo get warm js very hot
God I visited Alcatraz and the bay winds felt like they were piercing through my hoodie, like cold needles 😂 never appreciated San Diego more
Give me a 65 degree summer over 80-115 that the rest of the country gets.
Yes. It’s paradise compared to the horror summers in Texas and Arizona
As a San Franciscan, all I can say is Thank God! The best weather in the world. Love the chilly days, the fog, the fog horn blaring all night and bracing fresh air.
if you like SF then youll like canada better. its even cooler
@@highlymedicated2438what other areas in the world are pleasant during summer?
I visited San Francisco last July and wondered this very thing. Since it was summer and me being from the east coast, I packed a bunch of shorts and t shirts just to find out the high for that day was 62 degrees lol.
Haha, a very common experience. I knew what the temperatures were, but I still underestimated the wind chill.
Good for me, I hate the heat. I like the cold more
@@Shvetsario The UV index still gets up to about 10 in June and July, so it's cold and dangerous for your skin.
@@Monaleenian Wow so you don't get the warmth of the sun but still get blasted by UV rays ?
I was stationed in the U.S. Army in Hawaii for four years. I discharged out of San Francisco on July 8th..... I only owned shorts and t-shirts. The high for those three days was 47°, 46° and 49° overcast with 20 mph winds. I FROZE... I drove over The Golden Gate into a 100° desert.... The craziest weather changes in ny life... tropical Hawaii, cold San Francisco to desert in 72 hours...
This is so interesting! I remember coming to the US for the first time in 2011 as a teenager. I thought that California was very warm, so I didn't bring any warm clothes with me. When I arrived in San Francisco it was freaking cold, which surprised me a lot. The locals were laughing at me for not knowing that (but they were super kind). I bought a warm sweater at Pier 39. Anyhow, great city!
The joke here is always that you can find tourists because they’re in shorts but with a generic “San Francisco” sweatshirt that they had to buy in the city lol
@@TalussAthner Haha, that makes sense!
Our weather is totally different than LA, and SF is generally 5-10 degrees cooler than inland, locals know to always check the weather and have a windbreaker jacket at least
You should have asked me. So Cal native but I've been to San Francisco a bunch. For the L.A. area, summers can be hot, especially inland. Late winter and spring is best to walk around. San Francisco can also be kind of cold during the winter. A damp type of coldness. During the evening you could need a coat. Light jackets are good during the spring and summer, but something a bit heavier during the late fall and winter, but some warm days can sneak in there too. If you find you're not prepared, just go to Macy's and buy what you need. :)
@@danielzhang1916 the Bay is so diverse….I can be in San Jose “South Bay” and it will be so hot. 80s and up….Drive towards SF and you can feel it get cooler.
I lived in Monterey, CA for a time... it was definitely a weird climate! Never needed a/c in summer, if it started to get warm the fog would move in and
kept it quite cool, you needed a light jacket in July! In winter it never really got cold, you might have a light frost or two but you rarely saw it get below
freezing. One thing... the wind NEVER stopped blowing! It was not a climate I liked, I was glad to get back to the east coast to the normal 4 seasons.
that sound like an amazing climate for me
That sounds perfect to me
I used to live in Eureka, CA for 10 years, and that is exactly the weather type over there, you rarly get to see the sun, it's always cloudy, the most you get to see the sun is in the summer, even summer never gets hot or raise above 80F. I do like that weather though. I live in Oregon now.
If you go inland you get 4 seasons albeit different from the east coast with short 1.5 month winters and long bone dry summers.
When I first moved here to Santa Cruz from the east coast the fog bothered me, but now I like it.
Clear and well-detailed explanations on a very complex subject.
This was the clearest and best explanation of the phenomena I’ve ever heard. Been in SF for 15 years and I’ve learned bits and pieces of this but man…now all of my friends will think I’m a genius! 😂
I'm in Eureka and I knew most of this... but the reason for having an Indian summer or Sep-Oct being clear skies I never knew. Crazy it's just a reversal of winds.
Temperatures under 70 are actually mild in SF and other costal cities in North Cal. When it gets above 70 then you start feeling the humidity making it feel warmer unlike 70 inland where it feels nicer
The South/ some parts of the west Bay get extremely hot…EPA,Palo alto,San mateo,San jose….80+
very clear, comprehensive, and helpful explanation that i couldn't find elsewhere
As someone who used to live in SF who now resides back on the east coast AND is experiencing a good ole east coast summer, I miss the cool weather of SF 😌!!
Give me SF summer any day over the oppressive heat and humidity of the east
I remember when I had moved to the east from the Bay Area and people were wondering why I was so hot when they said California was hotter. I never explained to them that I was from the Bay Area and that California has multiple different climates. I don’t handle hot weather as well as I do cold weather.
You can experience a hot summer in the Bay too lol…..Literally go towards San Jose,West Bay….even the East Bay gets hot
@@SS-yj2le The Bay Area itself has different climates….massive difference from SF to San Jose to Antioch
@@shaunmckenzie5509 if you like SF youll like Canada even more. Its even colder
Notes from a local!
Story of a house in Sausilito, a town just north of the Golden Gate Bridge/SF, on the side of the hills that faces the inside of the bay. The microclimates were so intense that the property value of this very old house was higher than many of its neighbors -- because it was in the "banana belt", a small stip of Sausilito that, due to the shape of the pennisula/hills/steep grade of elevation, got much less fog compared to even a few streets to either side.
When you drive north from silicon valley to SF, or south from Marin to SF, there is a consistent point where the environment just changes. Cloudless blue sky becomes 100% overcast, and the temperature drops 20 degrees F, all in just a few miles. The flora changes from the 4 ft tall golden oat grass on western-facing hillsides (facing hot afternoon sun) and smallish shrubby trees on eastern-facing hillsides (facing soft morning sun), to Austrailian Eucaliptus and coastal Cypress trees, which are blown so hard by the coastal wind they cannot grow upright -- so they grow slanted from west to east. When you drive away from SF, the exact same change happens, so always take off your SF jacket BEFORE you start driving back north or south or you will sweat like crazy.
Driving north/south through the city is no big deal. Driving east-west is aboslutely insane. The incline is crazy and it all goes up and down, up and down, and you have to be careful at stoplights at the top of a hill, or your car might start sliding backwards down the hill. And yes the weather will change quickly here too, bc the clouds get caught on the same inclines you are trying to cross.
The bay itself is an estuary, where fresh water from the Sacramento river mixes with just the right propertion of salty sea water from SF. there are species that live in 1 area of the bay that would die in another area of the same bay just because of salinity differeces. It's the only river delta on the planet that is NARROWER where it meets the ocean than where the river delta is.
September-November is fire season, when the dead, 4 ft tall oat grass is dried out from summer heat, and we wait nervously for the first rain to end fire season, hopefully in october. If you hear thunder in August or September -- very rare but it does happen -- you've got a day or two before the wildfire smoke comes in. Dry thunderstorms mean lightning fires could pop up anywhere. But SF is the safest city in the Bay area from fire, as it's so wet, and the Great SF fire of 1906 was due to unsafe human infastructure being damaged by an earthquake, not wildfire. Same with earthquakes, not much real threat to SF there after 100 years of strict infastructure requirements. The natural disaster that would be worst for SF would be if something interfered with the fresh water supply to the city -- say, an earthquake on the Hayward fault or San Andreas fault.
Same deal for LA, which is one reason the state of CA will never be split into multiple states (even tho the state of CA alone has the 5th greatest economy in the world, more than the UK or India). The greater LA area is totally dependent on water from the ice packs of the Sierra Nevada mountains, east of the San Juaquin valley, and would never allow the state to be split between NorCal and SoCal, or they might just have to redo all their water infastructure like Las Vegas did to survive on very little water (and they'd never willingly do that, they love their orange tree groves and lawns too much lol). I'll admit the orange tree groves do smell amazing.
Do you know what the native landscape of the LA region was like? I've lived here my whole life, but I can't help but find it hard to imagine just how different the original grasslands and wetlands are from the current concrete and irrigation-dependent flora.
Such a very high quality channel is extremely hard to find on TH-cam…you can be deservedly proud of the content you present here…an uncommonly precious catch!!…
While great, there certainly is plenty of room for improvements.
I live in Humboldt Bay in far Northern California, and I always wondered why our weather was like this. I may be 5 hours north of SF but this was pretty accurate!
Its not that crazy everywhere….San Jose for example gets extremely hot
@@calidawg510 That bay is muuuuch larger than the humboldt bay though, probably like 6x the size. And San Jose is at the southern point past marshes, and is in a big dry valley. So it makes sense that it's really hot there! (I lived in different parts of san jose for 5 years)
@@DracowolfieDen My bad I didn’t know you lived here or were experienced with the Bay….Many people think of SF as representing weather across the bay which is just false….The far East Bay also gets quite hot….Really the most cold area is the peninsula.
How is Humbolt Bay? Is there fun things to do over there? I’ve always wanted go experience deep northern california.
I’m 19 but I’ve only visited Southern Cali, Central Valley and Mexico….Only lived in San Mateo county,Oakland and San Jose.
@@calidawg510 So true! I actually now live in the peninsula and it is indeed foggy like 70% of the time lol, but as soon as I leave that bubble it's almost always sunny.
Tbh humboldt is a fantastic place to visit if you're into nature. I know there are redwoods down in the SF bay, but the ones up there are huuuuge. And it's just a weird place full of hippies and art people. Lots of people compare parts of humboldt to santa cruz, but it's much more small town vibes up there and less rich people ahaha. Mainly deep northern california is huge, beautiful, and mostly empty with adorable small towns sprinkled around.
I hope you get to adventure more soon!!
@@DracowolfieDen You now live in the Humboldt peninsula or SF Bay peninsula?
Yea I’m a big nature guy I hope to visit up there one day…does it snow up there like Lake Tahoe?
Yeah I heard there are very different people up there including random immigrants from even Europe….Seems like a unique place…..
Wow--I've lived in San Francisco for 47 years and gripe about it every July. April & October are heaven, so I should be grateful. Great to have a thorough explanation, finally.
Any hot chocolate come with this video?
@Charankamal Padda Very adaptive attitude! I grew up in Denver, which boasts of having over 300 sunny days a year. But it's also the reason many people there develop skin cancer later!
@Charankamal Padda That's what I said--Denver's intense sun causes more skin cancer. You misunderstood something.
@@prototropo how is the weather in May?
It's so weird how spring and autumn are hotter than summer
@brandy1147 windy and cool. I was in shorts and crewneck and other people in coats lol
Please continue producing content. It is unique on youtube and extremely informational/entertaining!
0:49 if you go just a bit farther north or south the temperatures can be 90F+!
road tripping in California years ago, visiting from London - i took no warm clothes. in SF, i had to purchase a touristy sweatshirt - it was that cold! warmed up though, when we got to LA and Vegas!
Excellent use of maps. And thanks for including those very good sources. Yet another success at Casual Earth.
Great video. I learned a lot, and all within 8 minutes. Concise and precise.
Excellent work as usual!
Great video. Thank you so much for the information. Really well done. Impressively researched.
You have to be prepared for any type of weather along coastal California. It can change drastically in a few minutes, or if you drive only a few miles. Sometimes the hotter it is inland, the colder it gets at the coast!
I’ve studied SF weather for some time trying to find the best times to take pictures of the bridge and many areas within the city. I’ve found September being one of the best months to get that low fog in morning around the golden gate.
So happy I found this account thank you!
Wow! I never knew that summer was so cool in San Francisco, California! Thanks for sharing!
You don't even have to go so far as Stockton to see a more normal summer temperature. You can just go to another part of the bay like Oakland or San Jose. Using today as an example, it's expected to have a high of 69º in San Francisco (nice) 75º in Oakland and 80º in San Jose. Not as high as the 86º in Stockton today, but still noticeably higher than San Francisco.
Yup. When you go thru the Caldecott Tunnel you can stick your hand out the window in Orinda and then again in Berkeley 2 minutes later on the other side of the tunnel and feel how much cooler it is.
Absolutely brilliant video!
You don't have to go to Stockton for the temperature difference. On many days you can ride BART, our local S-Bahn, from Daly City through San Francisco and on to Walnut Creek in 53 minutes and go from 65F to 90F or better.
You have very binge-able videos! I can't stop!
Your videos are way too good for a channel with 9k subs
I grew up in California and the microclimates are astounding it can foggy and cool on the coast and sunny and hot just 10 miles inland. Most beaches at San Francisco's lattitude are swimable but I always needed a wet suit when swimming in San Francsco Bay, the ocean is rarely much above 50 degrees. Sacramento is hot most of the time but a few days each summer the sea breeze is strong enough to bring cool air and morning mist as far inland as Sacramento. The temperature would sometimes suddenly drop alot at the end of a heat wave when a strong sea breeze developed and the hot continental air was replaced with much cooler marine air. Normally the higher you go the cooler it gets but the opposite is true in the Bay Area hilltops can be sunnier and hotter than the coastal lowlands and you can look down on a sea of fog. Lake Tahoe at 6,000 feet elevation was warmer and more swimmable than the San Francisco Bay. I enjoyed swimming in Lake Tahoe the water was crystal clear and you could see down like 60-80 feet, when the water is this clear it looks shallower than it is it might not look very deep when you are actually in 30 feet of water.
We have highs of 36C in Metro Vancouver BC today remaining in the 30’s for the rest of the week . South in San Fran it’s 20C ugh I’m in the wrong city lol . One would think Canada would be cooler lol. The humidity here is sickening! Last summer we hit 49C in BC interior 46 in metro Vancouver absolutely ridiculous heat!
How was the humidity
SF has a unique climate that's for sure. 20deg highs in summer, but you drive 45mins out of the city and it's like 35c
SF is warmer than Vancouver though. For example, the highs in "metro" San Francisco hit at least 38C today (late august), and the city-proper hit 32C (on the east side, while the cooler ocean side topped out at around 27C). Average high in SF-city proper is 18, vs 14 in Vancouver city. The average low in SF is 11, vs 7 in Vancouver. Daily mean temperature is 14 in SF, vs 10 in Vancouver. Record high for SF is 41 vs 34 for Vancouver. Metro SF has also seen record highs of at least 46C, same as Metro Vancouver. Vancouver city-proper is usually a little warmer during the summer than SF city-proper though. The fog really confuses people when it comes to SF weather lol
@@shaunmckenzie5509 Don't forget though, that as the video mentioned, there can be large temperature variations just in the city-proper. Today at midday, for example, it was 27 degrees on the west side of the city, and 32 degrees on the east side. And then yeah, even farther inland, in the suburbs, it was approaching 40C.
I did an August road trip around california and nevada, ending in SF. It was sorching hot every single day, and then i got SF, and had to wear a jacket lol. I also noticed the eastern side is much sunnier, while the coast was foggy every day. I was getting sick of the heat, so i actually liked the cool weather in SF.
It's usually foggy and monochromatic west of Twin Peaks in San Francisco. It's foggy right now as I type this.
Unfortunately SF is now capital of the world of homs : homeless and the homos.
Yup! I live in the Sunset District yet work near the Financial District in SF and it's a night and day difference. It'll be misting with a heavy blanket of fog outside my house while next to my work it's clear skys and sun.
@@MaxM227Which do you like more the mist with a heavy blanket of fog near your house or the clear sky and sun ? I visited SF in 1999, 2003, 2005, 2008, 2011. From the very first time I was bewitched by the surreal mysterious weather and the fresh marine air. I also ate the best food in random restaurants. I like the spanish new world mission style and anything and wanted to move to SF. I was actually there to interview with Intel in 1999 but to my surprise they didn't extend an offer to me, neither did AMD. I was a top student and got offers elsewhere. To be honest i am quite sure, the dominant Indian and Asian engineers population in the valley both immigrants themselves were racially biased against a European immigrant like me that wasn't american. They wanted immigrants from their origins, especially the Indians i think.
Now even if had the opportunity i would absolutely no longer want to move there because it has become the center of ideologies that are degenerate, morbid and nefarious for society and families.
I far more enjoy the misty fog rolling over the hills. It adds a mystique and wonder to the peninsula often lost in modern-day life.
I'm sorry to hear about your failed pushes into AMD and Intel here in the city. I know the market was competitive back then, and it's even more so now!
It's also understandable why you wouldn't want to move here. It's true; SF is on a downturn, and crime has risen since the pandemic.
In terms of ideology, you'll be surprised to find that a surprising sum is actually quite moderate politically. Yes, it does lean quite heavily to the left (which is partly responsible for the day-to-day downturn)
But the average person you'll meet on the street is open-minded and easygoing. Many people are open to heavy police expansion and strict cleanup of homeless populations. Sadly, corporate media on both sides of the spectrum have divided our country. But the reality will always be more moderate even when you sit down with someone in SF or on the opposite side of the spectrum in say the Deep South.
Can you make a video about why Hokkaido Japan is so cold while Cote d’Azure France is hot despite being in the same latitude?
France gets that gulf stream along with the Mediterranean waters being quite warm. Versus Hokkaido which has much more continental influence from Siberia while lacking gulf stream influence. Only having that sea of Japan current which doesn’t provide as much warming. Water temperatures also get much colder in winter. Colder water also comes from the sea of Okhotsk which regular brings ice flows and has ports freeze over. That region of France also has the influence of the Alps mountain region that keeps out colder air from farther north and east.
Same weather back home in my city Agadir, Morocco, currently I live in the east coast (Dmv area) I kinda miss those foggy summers 🥺 and cold summer nights
That place has a perfect climate
This is the BEST explainer and video about how of SF weather is!
We lived in San Francisco for 5 years. “Karl” was our roommate! 😂 We saw him every day for those 5 years. We were on the foggy side of the city. We absolutely loved the late summer, early fall! We left there because… well, it’s _San Francisco._
We now live in Reno, NV. I’m in the mountains, at the bottom of a hill. I get the cold air every night, rushing down the hill, like in your first video about holes. Maybe I should give it a name, too? I’ll shall call him Max. As in *Maximum* cold! Don’t get me wrong. It’s still great in the summer and early fall! Just like in SF, but with less 💩
Interesting! I’ve noticed microclimates in my own city (Christchurch, NZ) because of the hilly peninsula influencing wind and rain patterns.
SF stores sell a lot of sweaters and hoodies in the summer months to the unsuspecting tourists who incorrectly assume it will be hot.
Have you considered doing a video about the southern Appalachian mountains? We have some unique microclimates here!
I like how you kept Sausalito, my hometown, mostly in center frame in almost all the clips you filmed at the Marina Green. Nice video
what is it like to be from saulsalito!? ive only been to that really touristy spot, i cant imagine saying im from there
Very well explained. I had always wondered why San Francisco weather was so similar to my hometowns weather, when most of california has a dry desert climate. I live in the city of A Coruña in Spain, we have an oceanic climate heavily influenced by the sea since we live in a peninsula. It’s slightly warmer than San Francisco since summer high averages are about 22-23 °C
Hello from Granada down south. I guess it's no surprise to most people but I always viewed Spain and California as geographic twins. Dry, sunny, warm south, hot interior, cool rainy and forested north. Even Ordesa/Monte Perdido National Park is like Spain's answer to Yosemite Valley. Y'know, except spain's cities are far more beautiful for like 1/4th the cost so we know who wins 😉
Most of California is not a desert climate. Especially northern where only a small area in the northeast has any desert in the northern part. The Iberian peninsula and California have very similar climates. We also have somewhat inland climates that border or are oceanic that are warmer than San Francisco.
@@SS-yj2leEverytime I see native californians showing what they think is green nature, i see a desert with water dried plants. I consider California to be a desert except on the coast.
Don't know how as we have the tallest trees in the world.@@ericastier1646
@@ericastier1646I don’t think Spain, italy and Greece are considered deserts because California has a the same climates as those countries
I remember one year when San Francisco hosted the (baseball) All-Star Game at Candlestick Park, aka The Abomination By The Bay, aka The Big Chill. Most of the fans were dressed more like it was winter. Made me laugh.
For reference, I'm familiar with California's coastal peculiarities. Used to spend summer weekends in Eureka to escape the Sacramento Valley blazing heat.
Just subbed. Liking your channel. I agrew up in Berkeley and know the Bay Area microclimates very well. Neighboring Oakland is always a little warmer than Berkeley even though they border each other but Berkeley is normally slightly warmer than San Francisco.
Half Moon Bay’s average high temperature for the month of July is even slightly cooler than SF’s average high temperature for that same month. The average high temperature for Half Moon Bay for the month of July is only 64 degrees. Santa Cruz’s average high temperature for that month is 10 degrees warmer because it’s on a south facing coastline. 66 degrees is the average high temperature for the hottest month of the year in Half Moon Bay. SF’s average high temperature for the hottest month of the year is 70 degrees.
the Bay of California is a miniature Mediterranean sea
I've lived in the East Bay (Oakland) since the late 70's and I remember that all through the 80's and much of the 90's the summer days always started out with fog that dissipated around midday. I haven't seen anything like that it the past decade. Once this summer there was a light touch of fog just before sunrise that disappeared before the sunlight. So we use the word "weather" for day to day changes and the word "climate for century to century changes. Should we have a word for decade to decade changes?
East Bay is still warmer than SF….South Bay gets heated
Thank you! I've lived in the Bay area for 27 years and always wondered why it's sunnier on the coast in fall/winter. Now I know!
Excellent material 👍There must be exceptional biodiversity around San Francisco
Made my day listen to climapolitic geography
What an awesome channel! I worked as a commercial fisherman for five years out the port of San Francisco(I’m also a north bay native) and this video explains it precisely as to the climate and natural magic of this truly amazing,unique and beautiful place.
Fascinating.
As a east bay native this is accurate. We have late summers. On summer days the sun may come out about 11am-12pm
I've been thinking and examining a lot about bay area climate lately, how its different even than Croatia or Turkey or Israel or Chile or Perth or anywhere else with similar desert/water and latitude mixtures. This is a great video.
"Here come those Santa Ana winds again" 🎵
The micro climates that we get in california from the fog is almost similar in the sacramento valley toward higher elevations of the sierra- cascade region. It would be 110°F in Redding but go up to 5500ft in elevation, its a perfect 80°F degrees. A diference of 40 miles. Comes in handy to be the heat.
thanks for the explanation, I used to live at Pointe Reyes a peninsula an hour north of SF and the weather there is even weirder. It is the western most point of the continental US and one of the windiest places. Similar microclimate situation, the peninsula is tomahawk shaped and covered in hills and ridges. Drive 5 minutes on that place and experience a whole new climate. The weather forecast is almost always wrong for the family house. It is crazy watching the clouds out there, they move so fast you can see them whipping by above your head but the clouds are always closer there than anywhere else. And I love driving to SF on a sunny hot day and getting there and the Golden Gate is shrouded in mist.
5:00 Oooh! I used to live in that red fringe!! Yeah, there was a lot of damage there in 1989.
Similar thing may be going on in Lima, Peru. Would be cool to know what happens there
They have the Humbolt current and also possibly an upwelling. It is actually a similar phenomenon that causes it to also have bigger seasonal temperature shifts despite being so close to the equator.
I lived in the Bay area for most of my life and never heard anyone refer to the fog as Carl.
I’m from the Bay as well and have also never heard it either. Maybe a local thing.
That's because it's Karl, not Carl.
I live in the city, and I've heard it but not for a while. The fog does have a twitter account too
I grew up in San Francisco and the summers were terrible.
Well made video about the micro climates in the Bay Area. People that do not live here do not understand how it can be so cold in the City in the "summer time" but warm and nice in September. I have lived in the Bay Area most of my life and have tried to explain this phenomenon to no residents and usually fail to get the point across. Your video is excellent at explaining this. (BTW, the locals pronounce "Diablo" Die-ab-low" and not "Dee-a-blow".)
Actually, I think the pronunciation of Mt Diablo has shifted in recent years to sound more like the Spanish pronunciation. It was definitely Die-ab-lo at some point but now Dee-ah-blo seems to be the norm
Moved from Scottsdale, AZ to Fort Bragg, CA recently... talk about weather shock!
Hello from Santa Cruz on Monterey Bay. Very cold foggy today and only got sun at 2pm. Could you help explain why it will be 58 on the beach here and in the Santa Cruz Mountains like Felton its 80! We frequently have a 20 pt spread between these very short distances. We have exceptionally steep grades in the Valley San Lorenzo Valley. Thanks. Tourists frequently get here and look at me like I can explain it or fix the freezing fog.
The Central and Northern Californian climate is not that different from the climate in the Portuguese coast. The difference between more coastline towns and inland cities is quite striking, with a big example being Sintra and Lisbon.
I love San Francisco weather in the summer. I love cool breezy weather.
Duluth, MN is similar to this too
You'd never wear that kind of jacket in sf. But its more cool rather than cold.
I have family from Norway that came to visit us in SF one summer. We took them on a tour of the City and they were shivering the entire time. They’re from the northern part of Norway, practically the Arctic Circle, and they told us they’ve never been so cold in their entire lives.
They figured California in the summertime was going to be warm so they packed accordingly. I guess we should have told them to pack their winter clothes.😂
what’s hilarious is it’ll be cold and foggy in sf, but literally 75 and sunny every day across the bay. you can see the clouds smother only the peninsula
living in central valley, you have no idea how night and day difference is take a 2 hour drive to the bay area and be able to wear any warmer clothes and then drive back and then having take all that off. its such a different world compared to the valley lmao
if you like places with surprisingly strange weather, you should explore how in Acre - Brasil, sometime, at 10o latitude, the weather goes below 15oC
Aug, 25 '22 As I browse the high temperatures around the US/ see the heat-waves engulfing Western Europe and now China- Good 'ol SF still- still hangs in its own climatic temperature zone of 65-66F and dats it!
I used I live in SF wayyy back in the early '80's as I had an international guest house. During the summer's I'd make every excuse I could to Get Out of SF- wine tours up to Napa / river rafting up in the Sierra's- even mere Bar B Q's over to the Berkeley Hills etc.
Yeah- I do miss SF- but the 'fog' seemingly all the time is rough!
Hang in there San Franciscans for as Oct-Nov. is coming and the rest of the nation starts to get uncomfortably cool to cold your fog will Stop and you'll have the Best weather in continental USA!
This happens all along the coast of Pacific Northwest. The Pacific Ocean keeps the summer month cool and winter months mild.
I usually need to turn the heat back on in July. I always warn visitors to bring jackets and winter wear for the summer.
“The coldest winter I spent was the summer in San Francisco.” Mark Twain.
San Francisco climate is obviously influenced by the almighty Pacific Ocean. that's why summer's temps in Frisco are pretty mild with temps ranging between high 60's and low 70's.
"The coldest winter I've experienced was a summer in San Francisco".
The reason those who live in sweltering climates requiring air conditioning for mere survival think 66F is "cold" is because their point of reference is polluted by their own experience. 66F is nothing other than "temperate" ever. Also San Francisco does get cold sometimes in winter, where the daytime high may only reach 58F. By comparison to the rest of the country, that too is temperate. San Francisco's temperate climate is one of the top driving reasons for San Francisco's popularity.
Native here and walking behind tourist who was freezing wearing shorts and said to his buddy “Let’s drive to L.A. for a day” Oblivious to the fact L.A. is a six hour drive 🙃
good I hate the weather at summer like 30 degree is so
The perfect summer weather. Not cold...cool. In my 11 years there it hit 90-degrees...once.
"That doesn't mean this is the perfect side of the city to live, even though it's sunnier." That makes it the worst side to live. Screw the sun and screw summer.
I've watched a video about an African region that captured fog condensation for water. Would San Francisco Fog which is so prevalent not make it ideal for water collection in San Francisco to other areas of California?
Just a note the fog isn't named Karl. That's just some guy with a Twitter account.
One of the few places where you can wear a winter coat in August. Mark Twain was right when he said that the coldest winter that he ever spent was the summer in SF.
I've lived here all my life and I've never heard the fog referred to as coral, choral?
It's Karl ...😊
❤❤❤❤
eyyyy, Stockton shoutout! Help us, we're dying here! It's too hot!
Sounds like Duluth- Superior climate on Lake Superior.
Interesting hearing that for that area. I am from the Bay and might travel there one day.
Is 66F degrees cold? I think is is very comfortable. I love temps in the 60's, not too hot or cold. Cold starts in the 30F's.
Light brary..
19c is really good weather...explanation, I'm british.
That’s not fog!,its smug!
