Best Time To Visit San Francisco
A month-by-month guide to weather, crowds, and travel conditions in San Francisco, USA.
About San Francisco
San Francisco packs a peninsula with forty-eight hills, two bridges, the country's oldest Chinatown and a fog pattern locals treat as weather planning. Cable cars still climb California Street, Golden Gate Park runs the width of the avenues, and the bay's microclimates mean summer visitors pack winter jackets — the city's most reliable travel advice.
