Climate information

Get the jacket ready, as winters in San Francisco are wet but mild – rarely at or below freezing, usually hovering just below 10°C/50° F (January is coldest). March and April frequently see rain. Summer fog keeps the average temperatures below 20°C/68°F– it's not uncommon to have overcast skies and slightly chilly weather in the dead of summer, but smart visitors always have plenty of layers handy, and a warm café or museum is often nearby. The best time to come is during the warm, sunny months of August and September, or slightly cooler October.
