San Francisco woke up to a surprisingly sticky start today, with mild temperatures in the low 60s and high clouds already drifting overhead. For late February, it is a clear step out of the usual playbook, with inland neighborhoods expected to warm into the low 70s while the coast hangs back in the cooler zone. Skies should stay mostly sunny this afternoon with light winds, setting up a comfortable, if unusually warm, day for park time, neighborhood walks, and errand runs.
Afternoon Heat and Isolated North Bay Storms
The airmass parked over the Bay Area is unusually warm for this point in the season, and forecasters say there is a slight 15 to 25 percent chance of showers and isolated thunderstorms across the North Bay this afternoon. Any action that does pop up is expected to be short lived and mainly focused on higher terrain, with little meaningful rainfall expected. For official guidance and the latest timing updates, see the National Weather Service San Francisco.
Timing and Temperatures
Temperatures are set to climb through the morning and peak by early afternoon, with hourly forecasts calling for highs near 73°F in inland spots and mid 50s to low 60s along the shoreline. Winds will stay on the light side from the north-northwest at about 3 to 7 mph, then readings slip back into the low 50s overnight. If your plans take you near or on the water this evening, a light layer will still be your best friend.
Sunday Into Next Week
Tomorrow brings a noticeable cooldown and a higher chance for light rain in the North Bay, with measurable rain looking likely for higher terrain and only spotty drizzle expected elsewhere. After that, the pattern trends warmer and drier by midweek as offshore flow returns. Forecasters also note rising fuel dryness and elevated fire weather indices early next week, so anyone considering outdoor burning should keep an eye on local rules and restrictions. More details are available from the National Weather Service San Francisco.
What To Do
Stay hydrated if you will be outside this afternoon, and do not leave children or pets in parked cars, even for a quick stop. Pack a light jacket for cooler waterfront evenings. If you are heading into the North Bay hills, be ready for a brief heavy downpour or a rumble of thunder, and move to shelter if you see lightning.
