In December, San Francisco averages a high of 57°F (14°C) and a low of 46°F (8°C). Most runs feel like about 52°F (11°C) once you factor in a typical morning or evening start, so dress for that number rather than the thermometer. Cool, foggy, and remarkably steady — San Francisco rarely gets hot or truly cold.
