Fire Weather Planning Forecast for the San Francisco Bay Area and
Central California Coast
National Weather Service San Francisco Bay Area
254 PM PDT Wed Sep 3 2025
.DISCUSSION...A generally benign weather pattern continues through
the next week with a gradual cooling trend in the forecast. The
marine layer will deepen through the next few days, resulting in
more inland stratus, possible coastal drizzle, and improving
overnight humidity recoveries in the hills outside of the highest
peaks. Clouds will retreat to the coast each morning and breezy
onshore winds develop each afternoon, with gusty conditions
through favored valleys, gaps, and exposed ridges.
Note : All winds are 20-foot Winds Unless otherwise specified.
Thunderstorms imply strong, gusty and erratic winds.
