August in San Francisco

San Francisco weather in August is sunny and mild during the day. The nights are cool with Karl the Fog hanging over the city most of the time. August is a pleasant month with temperatures in the range of an average low of 56 F and an average high of 72 F.

As with most months, it’s always best to wear layers during your visit. Once the sun comes out, it may take a few hours for that nightly fog to burn off. It almost always does, although some days it hangs around longer than others.

City Guides always recommends to please wear comfortable walking shoes on our tours. See you soon on the streets of San Francisco!
