Best Time To Go
Visit San Francisco in September or October for the most reliably pleasant weather and fewer crowds. Come in July and August for your pick of outdoor festivals and events. Spring is also a great time to visit, but expect the fog to roll in with a cool ocean breeze in the afternoons. During the annual Bay to Breakers footrace, held every May, some 75,000 runners and walkers, many in costume (and a few in their birthday suits), tackle this 7.46-mile course. The event also happens to be the city’s biggest (moving) party.
The eastern side of San Francisco is packed with walkable neighborhoods, if you don’t mind scaling a few hills. Use the BART (Bay Area Rapid Transit) subway system to get from downtown to the Mission District, SFO, or even the East Bay quickly and affordably. Regular Muni buses also offer an easy way to get around the city. Taxis, Ubers, and Lyfts are also quite common.
September is on average the hottest month, with an average high of 70°F (21°C). January is the coldest month, with an average high of 57°F (14°C).
Know Before You Go
This is a city where the weather changes on a whim and microclimates create varying weather patterns across the hilly terrain. Locals know to pack a few extra layers (a scarf and a light jacket should do the trick) before heading out. It might be sunny in the morning, but you never know when the town mascot, Karl the Fog, will crash the party.
