San Francisco starts Sunday in the upper 50s with a slight chance of drizzle before noon, followed by partly sunny skies. The high should reach about 62 degrees, though temperatures will be below late-September normals, keeping the day cooler than usual.
Drizzle Gives Way To A Breezy Afternoon
Morning drizzle should remain spotty, with only a 20% chance of precipitation and no sign of a meaningful rain event. West-southwest gusts could reach 22 mph. The National Weather Service discusses possible 20–25-knot gusts near SFO.
Sunday night will turn partly cloudy with a low near 54 degrees. Coastal cloud cover could return around the Bay overnight, so anyone heading out early Monday may want a jacket even as the week begins to brighten.
Sunny Monday Leads Into A Warmup
Monday brings sunny skies and a high near 70, followed by warmer weather Tuesday and Wednesday, with Wednesday's high expected to reach 76 to 77 degrees. Thursday and Friday should settle back near 70, with mostly sunny skies.
The updated outlook is a sharper turn from the cooler Sunday forecast published Saturday by Hoodline, adding a better-defined drizzle chance and stronger afternoon winds. Boaters should also note that Small Craft Advisories are posted for portions of the nearby coastal waters, where gusts and choppier conditions are expected.
