How cold is it really in the summer in San Francisco?

San Francisco summers are a bit of a surprise for many visitors! Unlike the rest of California, it doesn’t get super hot here. You’ll probably experience temperatures in the 60s to low 70s°F during the day, but it can feel chillier, especially with the famous fog rolling in. Even though it’s summer, it’s a good idea to pack layers, a light jacket or sweater for the evening is always a smart move. It’s not the sun-soaked California you might expect, but that cool breeze by the bay makes it all part of the charm!
