Best Time to Visit San Francisco

When to visit San Francisco

September–October is the sweet spot — warmest days (18–23°C), least fog, low humidity. May–August fog blankets the coast most mornings; bring layers year-round. November–March is cool (10–15°C) and rainy but hotel rates drop. Fleet Week (early October), Outside Lands (August), Pride (June) and Chinese New Year (Jan/Feb) are the peak-price weekends.

What each season changes

SF packs a full US city trip into 121 km² — walkable Downtown, Pacific coast, gateway to Napa and Yosemite, all in a week.

Season and price

Hotel rates in San Francisco follow demand more closely than weather. Shifting your dates by a week either side of a peak period often moves the nightly rate more than switching hotel category — check live prices for both before committing.

Seasonal planning tips

• Pack layers year-round — SF can go 12°C to 24°C in a single afternoon as fog rolls in.

• Tipping 18–22% at restaurants + SF Health Mandate surcharge often on bill (already tip-inclusive-adjacent).

• Never leave valuables in parked cars — smash-and-grab is the #1 tourist issue city-wide.
