San Francisco's Climate

San Francisco has a cool-summer Mediterranean climate shaped by the Pacific, with a remarkably narrow temperature range that rarely tops 26°C or dips below 7°C. Summers (June–August) are dry yet famously shrouded in the marine fog locals call 'Karl,' which rolls through the Golden Gate and keeps many days chilly and breezy; the rainy season runs from November to March. Autumn (September–October) is usually the warmest, clearest stretch of the year. This page offers an hourly and 14-day forecast plus detailed metrics for humidity, wind, UV index and air quality (AQI).

Frequently asked questions

Does it snow in San Francisco?

Almost never. Measurable snow in the city is extraordinarily rare, with the last significant fall back in 1976. Winters are defined by rain and fog, with overnight lows seldom below 5°C.

When is San Francisco's foggy season?

Fog is thickest in summer, from June through August, especially in the mornings and evenings as cold Pacific air meets warmer land. That's why July often feels cooler than visitors expect.

What is the best time to visit San Francisco?

September and October, when the summer fog lifts, skies clear and temperatures turn pleasantly warm. This 'Indian summer' is typically the sunniest period of the year.

Which months are wettest in San Francisco?

Rain concentrates from November to March, with December and January usually the wettest. Summers are nearly rain-free.
