Fire Weather Planning Forecast for the San Francisco Bay Area and
Central California Coast
National Weather Service San Francisco Bay Area
255 PM PDT Fri Jul 18 2025
.DISCUSSION...Warming and drying conditions continue into the
weekend as the marine layer compresses and onshore flow see a
slight decrease. The marine layer will remain intact along the
coast keeping cooler and wetter conditions, but higher elevations
and more interior areas will still experience elevated fire
weather concerns as the marine layer fails to reach those areas.
Northerly winds will strengthen on Monday increasing fire weather
conditions, especially the East Bay.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
