Fire Weather Planning Forecast for the San Francisco Bay Area and
Central California Coast
National Weather Service San Francisco Bay Area
330 PM PDT Tue Sep 2 2025
.DISCUSSION...There remains a slight (15%) chance for isolated dry
thunderstorms across far interior portions of the district through
sunset. This poses the risk for lightning and gusty and erratic
winds with very little rain, if any, to accompany it. Good to
excellent relative humidity recovery is expected tonight for all
but the highest terrain of the Central Coast. The cooling and
moistening trend will continue through the week with the help of a
deepening marine layer that will bring much needed relief.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
