San Francisco rolled out of bed under a chilly marine layer today, with downtown stations hovering near 52°F before sunrise. Skies should turn partly sunny later, with a high near 64°F and west-southwest winds cranking up through the afternoon, gusting around 20–22 mph. Expect the coast to cling to the gray a bit longer while inland neighborhoods shake it off by mid- to late-morning.
Foggy Mornings, Sunny Afternoons
A deeper marine layer of roughly 1,000 to 1,500 feet is parked over the city this morning, keeping shoreline neighborhoods socked in while much of San Francisco brightens by midday. A little mist or drizzle may show up along the immediate coast, but widespread rain is not on the menu. According to the National Weather Service, inland highs stay in the mid-60s while the beaches run cooler.
Afternoon Winds Pick Up
By afternoon, west-southwest winds will be flexing, generally 5–14 mph with gusts around 20–22 mph on exposed hilltops and bridge approaches. Cyclists and pedestrians on open routes should brace for a push, and drivers on higher spans may feel those crosswinds.

Boaters Take Note
A Small Craft Advisory is in effect for coastal and near-shore waters from Point Arena to Point Reyes and north of the Bay Bridge from 3 PM to 9 PM PDT today. Small or open boats should stick to sheltered waters and read the full advisory from the National Weather Service. Seas stay moderate through midweek before building later this weekend.
Looking Ahead
Warmer and drier weather moves in Thursday and lingers into next week, with highs climbing into the low- to upper-70s and potentially near 79°F by Monday. Plan on layers for the cool mornings now, then get ready for sunnier inland afternoons as the week goes on.
