Average Weather for San Francisco, CA - Temperature and Precipitation

That's why it isn't fair to compare the climate of Seattle to San Francisco esp since they 700 miles apart. The PacificNW is not a Mediterranean climate but the Pacific ocean modifies it in a way that is similar to San Francisco. Seattle is about 50 miles inland from the ocean [similar to Stockton, another inland harbor]. A mostly dry\ sunny summer [70-75F] and long cool wet winter [47F-51F].
Well it's not a direct comparison but it's one of the climates that comes closest. It's certainly not the same though.

Maybe I'm misunderstanding you here but it seems like there's a hint of a comparison with Seattle and Stockton? I hope I'm wrong.

Seattle has a totally different climate than SF -- SF is Mediterranean, which means more than 80 percent of rain falls within six months, and hardly any the other six months. Seattle has rain over a much longer period of the year, much like an improved version of London. Seattle is also prone to occasional ice and snow storms in winter. The lowest temp ever recorded in Seattle is around 0 F, while in SF it's about 26 F. The vegetation in SF is therefore distinctly Californian, with its palms and eucalyptus. The only downside of SF is its cool summers, but that's a microclimate; away from the ocean, the climate is more what we think of as Mediterranean.

don't worry, Gentoo, I am a California booster [some say "homer"] but even I wouldn't compared Stockton to Seattle. It's hard to say what city in the Pacific NW Stockton could be compared to re: climate [have any ideas?]. I only mentioned Stockton because it is also a deep water\ ocean-faring port [California produce is shipped from Stockton] and enough inland from the ocean to create a different climate. Both Seattle and Stockton are sheltered [so to speak] from the Pacific ocean by mountains. The Puget Sound is much wider thru the Strait of Juan de Fuca then the Golden Gate. And the San Francisco bay narrows again in the Carquinez Strait. But both cities are influenced by the ocean none-the-less. Stockton has the coolest summer in the Central Valley by way of that funnel of coastal air. Seattle doesn't contend with summer fog like San Francisco or much of the California coast.

There seems to be more differences than similarities between the climates of San Francisco and Seattle [I may be wrong, though

No, you're right, there are more differences between Seattle and SF. It's just within the US, outside of So Cal, Seattle would be the next closest. Other than that, the closest I could find would be Monterey. In San Diego the La Jolla and Torrey Pines areas are similar as those areas are prone to summer fog as well.

Right, certainly Monterey but not Santa Cruz for geographic reasons. Palos Verdes Peninsula but not Long Beach for the same reason. Pismo Beach\ Lompoc\ Newport Beach are other "fog belt" areas. But coastal Southern Cal is quite different overall than San Francisco.

This was making sense-the bolded parts-then when you go to Newport it stopped making sense. Newport-as with that entire stretch from the Port of Los Angeles in San Pedro down through Laguna Beach are offered extra protection from the fog (called the "marine layer" in SoCal) due to Catalina Island disrupting the process.

You could very well be right. Long Beach is south-facing with the Palos Verdes mountains to the northwest. Long Beach is often as warm if not warmer than downtown LA due to the obstruction of the westerly Pacific breeze. But south of Long Beach\ Los Alamitos bay there are no mountains until you reach Newport Beach\ Costa Mesa. The clouds sort of hang around longer in Newport compared to Laguna Beach due to the mountains north of Laguna. Newport Beach is cooler than Laguna during summer but warmer at night than Luguna all year long. Further north in the Santa Monica bay, Malibu is sunnier since it faces south with the high mountains behind while the South Bay is cloudier. These are micro-climates few people even know exist but make California a fascinating place of different weather over a short distance.

Miscro climates are really something aren't they? It's funny that we got to talking about this here because the Bay Area and even the city of SF can be quite different from one place to another. The Sunset district is poorly named because you don't often see the sun there at all. The eastern half of the city is certainly sunnier and warmer than the sunset. In summer, temps in the sunset hover in the low 60's most of the time. In the eastern parts of the city the rise into the high 60's and low 70's. Then you cross the bay and things are varied even more. Berkeley is sunnier than SF but not too much warmer as it sits directly across from the Golden Gate and anyone who's lived in Berkeley can tell you that there's often a stiff breeze blowing off the bay. Berkeley usually stays in the low 70's in summer. Oakland is generally warmer overall and mid 70's are typical in most of the city. Go over the hills behind either city and temperatures really increase. From Walnut Creek to the Sunset district, temperatures may very buy over 30 degrees! It can be 94 in Walnut Creek and 62 in the Sunset.

San Diego too has it's microclimates. The coastal areas vary just like they do in LA. Point Loma is cooler than most of the rest of the city but isn't as prone to fog as La Jolla. La Jolla sticks out more and if you're in Pacific or Mission Beach areas, you can often see a cloud hanging on La Jolla just to the north on some days. Torrey Pines grow where they do just north of La Jolla due in large part to this fog in the area and they mention that at the visitors center.

Thanks for the additional info, Gentoo. The difference between downtown San Francisco & the airport is several degrees also. But due to the relatively narrow gap in the coastal mountains the wind funnels into San Francisco & can be very chilly on a summer evening. The wind seems to settle down considerably once past Pt Conception in coastal SoCal. And even though it can be overcast the temp is often quite pleasant along the coastline [even at night] down here.

Yes that's true and the drier air in norcal (lower dew points) causes the temperature to drop like a rock when the sun sets.
