San Jose rolled in today under a gray blanket, waking up to cloudy skies, cool air around 52°F at Mineta San José International Airport, and stubborn pockets of fog that lingered into midmorning. A slight chance of light showers overnight has mostly come and gone, and most neighborhoods are on track for brighter, mostly sunny skies this afternoon with a high near 66°F. Plan on overnight lows in the mid-40s, so you may want a light jacket for any late-night errands or dog walks.

Afternoon Winds Pick Up

By later today, west-northwest winds will start to flex a bit, generally in the 1 to 10 mph range with gusts up to 18 mph along the Bay and on exposed hills. Those gusts could make your after-work park hangout or patio coffee feel a touch cooler than the numbers suggest. For details on timing and any marine-related alerts, head to the National Weather Service.

Foggy Morning Commute

Patchy fog is expected before about 9 AM, especially in low-lying spots and along shoreline corridors where visibility can drop quickly and without much warning. Drivers should slow down, stick to low beams, and give themselves a little extra room and time. Cyclists and pedestrians should act as if motorists may not see them right away. The good news: the fog should burn off by late morning, clearing the way for a sunnier afternoon commute.

Boaters And The Coast

Small craft advisories are up for parts of Monterey Bay and nearby coastal waters from this afternoon into Tuesday night, with choppy seas and gusty winds making things rough for smaller boats. If you were planning to head out, it might be the day to reschedule or double-check that your vessel is secured until conditions improve. Local boaters and beachgoers can find full marine details and any updates at the National Weather Service.

Looking Ahead

Forecasters expect cooler-than-normal temperatures to hang around through midweek, with gusty winds, especially over higher terrain, Wednesday into Thursday, before a warming trend moves in Friday and into the weekend. Inland highs should climb into the 70s by Friday and Saturday, with overnight lows still dipping into the 40s.
