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.

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. 🌫😌🧡🖤

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.

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?

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.

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.

“The coldest winter I ever spent was summer in San Francisco”-Mark Twain.

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.

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.

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!

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...

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.

Give me a 65 degree summer over 80-115 that the rest of the country gets.

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! 😂

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.

Please continue producing content. It is unique on youtube and extremely informational/entertaining!

Excellent use of maps. And thanks for including those very good sources. Yet another success at Casual Earth.

Excellent work as usual!

So happy I found this account thank you!

Clear and well-detailed explanations on a very complex subject.

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?

Great video. Thank you so much for the information. Really well done. Impressively researched.

Great video. I learned a lot, and all within 8 minutes. Concise and precise.

Absolutely brilliant video!

very clear, comprehensive, and helpful explanation that i couldn't find elsewhere

You have very binge-able videos! I can't stop!

Such a very high quality channel is extremely hard to find on KZfaq…you can be deservedly proud of the content you present here…an uncommonly precious catch!!…

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!

I LOVE videos like this! Please keep making them! Im really into geography and as an oakland native now living in the super hot low desert down in socal, where it will be 123°F in the next couple of days, I've always missed that cool summer weather from the Bay Area.

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 😌!!

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

Your videos are way too good for a channel with 9k subs

This is the BEST explainer and video about how of SF weather is!

Wow! I never knew that summer was so cool in San Francisco, California! Thanks for sharing!

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

Interesting! I’ve noticed microclimates in my own city (Christchurch, NZ) because of the hilly peninsula influencing wind and rain patterns.

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.

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!

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?

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.

0:49 if you go just a bit farther north or south the temperatures can be 90F+!

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!

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.

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!

Fascinating.

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.

Have you considered doing a video about the southern Appalachian mountains? We have some unique microclimates here!

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 💩

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.

Moved from Scottsdale, AZ to Fort Bragg, CA recently... talk about weather shock!

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.

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

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.

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!

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.

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.

SF stores sell a lot of sweaters and hoodies in the summer months to the unsuspecting tourists who incorrectly assume it will be hot.

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".)

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.

5:00 Oooh! I used to live in that red fringe!! Yeah, there was a lot of damage there in 1989.

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.

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

Excellent material 👍There must be exceptional biodiversity around San Francisco

"Here come those Santa Ana winds again" 🎵

Duluth, MN is similar to this too

if you like places with surprisingly strange weather, you should explore how in Acre - Brasil, sometime, at 10o latitude, the weather goes below 15oC

Made my day listen to climapolitic geography

the Bay of California is a miniature Mediterranean sea

I NEED to move here A. S.A.P., I can't stand the heat/humidity!

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?

Similar thing may be going on in Lima, Peru. Would be cool to know what happens there

I love San Francisco weather in the summer. I love cool breezy weather.

As a east bay native this is accurate. We have late summers. On summer days the sun may come out about 11am-12pm

I lived in the Bay area for most of my life and never heard anyone refer to the fog as Carl.

I grew up in San Francisco and the summers were terrible.

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.😂

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 usually need to turn the heat back on in July. I always warn visitors to bring jackets and winter wear for the summer.

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!

You'd never wear that kind of jacket in sf. But its more cool rather than cold.

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

This happens all along the coast of Pacific Northwest. The Pacific Ocean keeps the summer month cool and winter months mild.

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

"The coldest winter I've experienced was a summer in 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.

good I hate the weather at summer like 30 degree is so

Just a note the fog isn't named Karl. That's just some guy with a Twitter account.

eyyyy, Stockton shoutout! Help us, we're dying here! It's too hot!

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?

“The coldest winter I spent was the summer in San Francisco.” Mark Twain.

❤❤❤❤

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 🙃

I've lived here all my life and I've never heard the fog referred to as coral, choral?

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.

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.

Sounds like Duluth- Superior climate on Lake Superior.

"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.

The perfect summer weather. Not cold...cool. In my 11 years there it hit 90-degrees...once.

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.

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.
