San Francisco is starting today cool, with temperatures near 62 degrees in the early morning. A slight chance of drizzle lingers through late morning, then the city should turn mostly sunny and top out near 69. The bigger rain story stays north of the Golden Gate, while the weekend forecast trends bright and gradually warmer.
The latest update sharpens that regional split from yesterday's outlook: San Francisco remains in the light-drizzle lane, while Sonoma and Marin counties face a more meaningful round of rain tomorrow. For city residents, that means a damp commute is possible but a full washout is not the leading forecast.
Drizzle Gives Way To A Breezy Afternoon
According to the National Weather Service San Francisco, drizzle chances remain slight before 11 AM today, before skies brighten. South-southwest winds will run 5 to 13 mph, with gusts up to 18 mph, and temperatures should slip back into the mid-60s later in the afternoon.
Thursday Brings The Best Rain Chance
Tomorrow looks mostly cloudy, with a 40% chance of drizzle before 2 PM and a slight chance of light rain around 3 or 4 PM; the high should reach about 68 degrees. The North Bay could see roughly a quarter-inch to a half-inch of rain, while precipitation chances drop sharply south of the Golden Gate.
After tomorrow night turns partly cloudy with a low near 56, Friday should be sunny and near 68 degrees. Saturday and next Sunday stay sunny or mostly sunny around 69, followed by a Labor Day high near 72 and a warmer next Tuesday near 75.
Light Jackets Still Belong In The Forecast
For today's plans, a light jacket and some wind protection should be more useful than a serious rain setup, especially near the waterfront. An umbrella may come in handy tomorrow morning, with the North Bay facing the wetter conditions; no watches, warnings or advisories are listed for San Francisco.
