San Francisco rolled in today with that classic cool, clammy start: temperatures near 52°F, damp air, and a small chance of patchy drizzle for the morning commute. Any light mist should fade by late morning, giving way to mostly sunny skies by afternoon and a high near 63°F. The immediate coast will lag behind under a rebuilding marine layer, while light to moderate west-northwest breezes pick up just enough to feel gustier on hilltops. Inland neighborhoods are on track for a warming, drying trend through midweek.
What To Expect Today
The best shot at spotty drizzle runs from about 8 AM to 11 AM today, with only light amounts expected and low odds of anything measurable in the rain gauge. Clouds should break up late in the morning, leaving mostly sunny conditions for the afternoon. Onshore winds will run around 3–10 mph as temperatures top out near 63°F. A light waterproof layer is still smart for the morning ride or drive, and a sweater will come in handy once that afternoon breeze kicks in. The forecast information is from the National Weather Service.
Coast Stays Cool, Interior Warms
The marine layer keeps the immediate shoreline on the chilly side while inland spots quietly warm up. Highs away from the water are forecast to reach the upper 60s tomorrow, and near 70–71°F by Wednesday. Some interior valleys could push into the 70s or even the low 80s later in the week as the atmosphere dries out.
Boaters And Bay Users
Mariners should note a Small Craft Advisory is in effect for outer coastal waters from Point Arena to Point Reyes from about 9 PM today through 3 AM. Wednesday. Exposed seas are expected to build into the 8–12 feet through midweek, so small vessels will face hazardous conditions; inexperienced boaters should avoid heading offshore and check with local harbormasters before leaving the dock. See the National Weather Service for the official marine statement and updates.
Tips For Commuters
Expect damp roads during the Monday morning commute, with drizzle lingering, and build in extra travel time while using low beams in any foggy patches. This afternoon, sunshine and lighter traffic create a more forgiving window for errands or outdoor plans, but a wind layer is still a good idea if you are heading to the waterfront. Sunglasses and sunscreen will earn their keep at inland parks as temperatures start to climb.
