About these readings

Rainfall in San Francisco, California 94103

These readings estimate rain near this ZIP’s reference point, not an average across the entire ZIP. Use device location or search above for a more specific area. Nearby streets can receive different amounts during localized storms.

Today starts at midnight in the America/Los_Angeles time zone. The 24-hour and 7-day totals are rolling windows through the displayed analysis time. Historical dates use local calendar days; the YTD graph compares the same completed dates with the 1991–2020 ERA5 average.

Local rainfall context for San Francisco, California 94103

San Francisco’s measurable rain is concentrated mainly in the cool season, when Pacific systems reach the Bay Area. Summer is typically dry even when fog is frequent. Hills, coastal exposure, and the path of each storm create strong local differences, so the 94103 reference point should not be used as a total for every part of the city or bay.

For a winter storm, compare the rolling 24-hour value with the daily table because the heaviest period may cross local midnight. Multi-day atmospheric-river events can make the seven-day total more informative than a single calendar day. Follow National Weather Service Bay Area alerts for flooding, wind, coastal hazards, and safety decisions.
