San Francisco has one of the strangest microclimates in the world, with the mountains and the bay and the ocean all surrounding it on three sides.
Mark Twain once (didn't, apparently, say, but it holds up) said "The coldest winter I ever spent was a summer in San Francisco."
- njarboe 9y agoThe main thing keeping SF cool in the summer is a cold ocean due to the current coming from Alaska, high coastal ranges north and south of SF, and the large central valley to the east. The air in the central valley heats up and rises causing a strong flow of cool air to move from over the Pacific Ocean, across San Francisco and the Bay, into the central valley. This keeps the Bay area relatively cool in the summers. Sometimes this flow is interrupted for various reasons and things can heat up quite quickly. Especially if the wind starts bring in hot air from the east.
