San Francisco started today, on the chilly side, with a cool marine layer, low clouds clinging to the coast, and neighborhood temperatures hovering around 51°F. By mid to late morning, the sun is expected to break through, and most of the city should warm to around 66°F this afternoon. West winds stay on the mild side, generally 3 to 10 mph, before overnight lows slide back into the low 50s.
Morning Fog, Sunny Afternoons
Low stratus rebuilt along the shoreline overnight and will drift inland through the early commute, then gradually scatter as inland pockets clear first. Expect reduced visibility near the water early on, followed by mostly sunny skies for the afternoon, a classic San Francisco two-for-one. According to the National Weather Service, the marine layer should thin out as the morning progresses and VFR conditions are expected to return for most areas.
Midweek Rain And Slight Storm Chances
The pattern starts to shift later this week. Measurable, generally light rain is most likely to arrive Thursday morning, April 9, with showers hanging on into Friday, April 10, and into Saturday morning. Forecasters are flagging a slight chance of isolated thunderstorms on Thursday and Friday, although the heaviest precipitation still looks most likely to remain offshore. For earlier discussion and timing context, see the one warm day before midweek showers crash back in.
On The Water And Commute Notes
Winds stay light through midweek, although exposed coastal spots will feel a bit more breeze, with afternoons generally around 5 to 10 mph and occasional gusts near 10 mph. Boaters should note that a small craft advisory is posted for parts of the central coast (Pt. Pinos to Pt. Piedras Blancas) from late afternoon into early Tuesday, so checking local marine forecasts before you head out is a smart move. The National Weather Service also cautions that a deeper marine layer overnight could slow the morning shoreline commute, so budget some extra time if your route hugs the water.
What This Means For Your Plans
If you are planning outdoor activities, the most reliable dry days appear to be tomorrow and Wednesday, April 8. From Thursday through Saturday, it is wise to have a backup plan that involves a roof. A light jacket will go a long way for cool, foggy mornings near the water, and you will want an umbrella handy once showers move in after Thursday morning. This forecast will be updated as models sharpen the timing and coverage of the midweek system.
