Weather: San Francisco Downtown station, 1 mi from San Francisco's center (NOAA 1991-2020 Climate Normals). People: Census ACS 2020-2024. Counts: CBP 2023, by county, paid-employee establishments. Population: Census, July 2025.
What San Francisco's weather means for nonprofits
Average highs never fall below 58°F, even in January, yet 7 months stay under 65°F, so in San Francisco a light hoodie or long sleeve is the volunteer layer for most of the year, not heavy fleece. Short sleeves get a narrow window: average highs reach 70°F only from September to October, so a long-sleeve participant shirt suits most event dates. Several months a year pass with almost no rain, so that dry stretch is the safest time for an outdoor fundraiser, and the rain plan can wait for the wet months. The wettest month, December, brings about 4.8 inches of rain, so keep it off the walk and run calendar where you can.

Ordering from San Francisco
Which participant shirt suits a charity walk or run in San Francisco?
Long sleeves for almost any date: highs stay under 65°F from November to May and peak at only 70°F in September, so a long-sleeve technical shirt makes a sensible default even for a summer race.
