SAN FRANCISCO, Calif. – Sunshine across the Bay Area will give way to a wet turn by Tuesday, ending a bright Columbus Day holiday with showers and a noticeable cooldown. Morning commuters and families returning to school after the long weekend should plan for slower travel and slick roads as the next Pacific system rolls inland.
According to the National Weather Service San Francisco Bay Area, rain develops Monday night and continues through Tuesday with a 90% chance of precipitation. Thunderstorms are also possible Monday afternoon, especially along U.S. 101 and the coastal hills. Winds could gust over 20 mph, creating minor travel impacts and reduced visibility on bridges and higher terrain.
By Tuesday, daytime highs will fall into the mid-60s with cooler air lingering midweek. Light rain will taper off by Tuesday night, but damp streets could affect the early Wednesday commute. Wednesday and Thursday bring a return to sun, mild temperatures, and classic fall conditions — perfect for post-holiday errands, pumpkin patch visits, or leaf-viewing strolls through Golden Gate Park.
Residents are encouraged to allow extra time for Tuesday travel, especially during school drop-offs and morning commutes. Secure outdoor decorations and charge devices ahead of the storm. Clear skies return late Wednesday, with another mild warming trend possible into next weekend.
