San Francisco is starting today under a damp marine layer and temperatures near 58 degrees, with a slight chance of drizzle before 8 AM. The clouds should retreat after sunrise, making way for mostly sunny skies and a high near 70. It is the sort of morning that requires a jacket first and sunglasses later.
Drizzle Gives Way To Sun
The National Weather Service expects today’s drizzle chance to stay at 20% or lower, while west-southwest winds run 6 to 14 mph and gust to 18 mph. Near the Bay and coast, low clouds may linger longer than in sunnier neighborhoods, but the city forecast turns mostly sunny by late morning. The National Weather Service says temperatures will remain near or slightly below seasonal averages within the marine layer through Thursday.
Afternoon Winds Pick Up
Winds will be lightest in the morning, then build through the afternoon, reaching around 12 to 14 mph by mid-to-late afternoon. Waterfront walks, bike rides and outdoor dining could feel cooler once the west wind fills in, even with the sunny skies. Tonight’s low is expected to be around 58 under partly cloudy skies.
Warm Wednesday, Cooler Weekend
Wednesday looks like the warmest day in the city’s near-term forecast, with mostly sunny skies and a high near 75, followed by about 74 degrees on Thursday. Then the pattern flips: Friday drops to around 68, and highs settle near 64 on Saturday and next Sunday before next Monday tops out around 62. The latest outlook now shows a cooler weekend than the earlier forecast covered by Hoodline.
Coastal Advisory Begins Tuesday Afternoon
For boaters, the National Weather Service has issued a Small Craft Advisory from 3 PM today through 9 AM Thursday for several offshore waters, as breezes strengthen and seas turn more challenging. Farther inland, temperatures will be warmer, while exposed coastal areas see stronger onshore gusts later in the week. Forecasters are also watching tropical moisture that could reach the Bay Area Friday into the weekend, although the current thunderstorm chance remains below 5% and no direct tropical-storm impact is expected.
