San Jose started today on the cool and clammy side, with Mineta San José International reporting about 52°F early this morning. Low-lying neighborhoods should be ready for patchy fog in pockets before 10 AM, especially in the usual trouble spots. Skies stay mostly cloudy with highs in the low to mid 60s and light northwest breezes. The calm will not last long: a storm system offshore is set to push in on Tuesday, bringing the main round of rain for the week along with a shot at thunder.
Morning Fog, Mild Afternoon
Patchy fog this morning is most likely in sheltered valleys and near the bay through the early commute, with visibility dropping at times on quieter surface streets and ramps. By the afternoon, highs should reach around 62–65°F, then fall back into the 40s inland overnight. Northwest winds are expected to stay on the light side, around 3–8 mph. That should keep fog from becoming truly widespread, but early drivers should still take it slow where the gray thickens.
Rain And Thunder Expected Tuesday Into Wednesday
Rain is likely to move in Tuesday morning, February 10, 2026, with showers and isolated thunderstorms hanging on into Wednesday. New rainfall totals on Tuesday will generally range from a tenth to a quarter of an inch, with localized amounts of a quarter to a half inch possible Tuesday night where heavier bands set up. Brief downpours and isolated thunder are on the table. For the latest timing and projected amounts, keep an eye on the National Weather Service.
Marine Conditions And Small Craft Concerns
Coastal waters and Monterey Bay are in for fresh to strong northwest breezes ahead of the low, and forecasters have issued small craft advisories for segments of the coastal waters. Gale-force gusts are possible in waters south of the Golden Gate, depending on the exact track of the storm. Boaters should secure loose gear, avoid exposed runs during the peak of Tuesday's winds and rain, and be prepared for rough seas and reduced visibility in heavier showers. Anyone heading to the coast should stay on top of advisory updates and treat jetties and rocks with extra respect.
Commute Tips And What To Bring
Drivers should expect slick roads from Tuesday into Wednesday and build in extra travel time for both the morning and evening commutes. A rain jacket or umbrella will be handy, and it is worth slowing down for standing water and sudden downpours that can cut visibility in a hurry. Check the latest forecasts before you head out, and consider shifting outdoor plans if they land right on top of Tuesday's heavier rain bands.
