Fire Weather Planning Forecast for the San Francisco Bay Area and
Central California Coast
National Weather Service San Francisco Bay Area
249 PM PDT Thu Oct 9 2025
.DISCUSSION...Fire weather concerns are generally low with
onshore wind, high humidity, low temperature, and rain in the
forecast. A weak disturbance will bring overcast skies and some
light rain to the North Bay Friday. Drier air will settle in
briefly this weekend with some gusty onshore winds both Saturday
and Sunday. These conditions will be short lived as a mush more
robust system brings widespread wetting rain the the Bay Area and
Central Coast early next week, with around 1" or more expected
from Monday-Tuesday. If the forecast holds, this significant
early season rain will bring roughly the normal precipitation for
the entire month of October, increasing fuel moisture
considerably.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
