San Francisco has a cool Mediterranean climate with dry summers and wet winters. At the downtown San Francisco station, the 1991-2020 reference averages range from a daily high of 58°F (14°C) in Jan to 70°F (21°C) in Sep. Monthly precipitation averages sum to 22.9 inches (581 mm) per year.
Summer fog and ocean air often keep coastal neighborhoods cool while inland areas are much warmer. September has the highest average daily maximum in the station climate table. Most rain falls in the cooler months, and neighborhood temperatures vary with marine-layer coverage and wind.
San Francisco's familiar coastal fog forms when moist air is cooled over cold ocean water. Marine air can enter some neighborhoods while sheltered areas remain sunnier and warmer.
