San Francisco, Calif. – Sunshine will dominate the Bay Area through Saturday, but the first days of October may bring rain. Residents should prepare for changing conditions with wet roads possible by late Sunday and into early next week.
According to the National Weather Service, San Francisco will warm into the mid-70s Friday before cooling slightly Saturday. Conditions stay dry until late Sunday when a weak system pushes in from the Pacific, raising the chance of showers after 11 p.m. Commuters should anticipate slick pavement on major routes, including I-80 and Highway 101, as the new workweek begins.
Friday looks bright with highs near 75 degrees and light afternoon breezes, perfect for outdoor events or travel. Saturday stays sunny, topping out near 71, but clouds will build late in the day. By Sunday, skies turn partly sunny with highs near 70. The bigger shift comes at night, when scattered showers may begin the first measurable rainfall of the fall season.
The system lingers into early next week. Monday and Tuesday both carry a chance of rain, with highs holding in the low 70s. While no flooding is expected, drivers should give themselves extra travel time and secure outdoor items ahead of gusty winds near the coast.
More updates may follow if the storm strengthens. For now, Bay Area residents can enjoy a mild weekend before preparing for a wet start to October.
