San Jose rolled under a blanket of patchy fog today, with local observers reporting mist and temperatures in the mid-40s. Low-visibility pockets settled into valley neighborhoods and along the shoreline before sunrise, making some streets feel more like a movie set than a morning commute. If you are heading out early, give yourself extra time and stick with low beams until the gray lifts.
Foggy Mornings, Sunny Afternoons
The fog is expected to burn off by mid to late morning, opening up to partly to mostly sunny skies and an afternoon high near 67°F. West-northwest winds will start off light, then build to about 1–12 mph with gusts up to 18 mph on exposed hills and bridge crossings. Interior neighborhoods should enjoy comfortably warm sunshine while the immediate coast hangs onto cooler readings.
Coastal Flooding And Beach Hazards
The National Weather Service is flagging a chance of minor coastal flooding during the high astronomical tide this morning for bayshore spots along San Francisco Bay, San Pablo Bay, and Monterey Bay. Low-lying walkways and shoreline parks could see brief overflow before the water recedes. Out on the Pacific, beaches stay dicey until tomorrow, as a long-period northwest swell keeps the risk of sneaker waves, strong rip currents, and breakers in the 14–19 foot range in play, according to the NWS Bay Area. Staying well back from the waterline is strongly advised.
Boaters And Ports
Small craft advisories kick in later today and run until tomorrow, with rough outer waters and fresh northerly breezes that are expected to relax by Tuesday. Mariners are urged to postpone nonessential trips and secure loose gear before conditions ramp up. For precise high-tide times or any local port advisories, check the NOAA tide tables and your harbor master before you launch.
Commute Notes
Drivers should pad their morning schedules and keep to low beams in fog-prone stretches, taking it easy on slick on-ramps and bridge approaches. By late afternoon, gusty conditions could nudge high-profile vehicles on exposed routes, and light gusts may ripple through ferry service, so factor that into travel plans.
Looking Ahead
From Monday through Wednesday, a warming trend sets up, with daytime highs climbing into the upper 60s to low 70s and dry weather dominating the short-term outlook. No significant rain is on tap through Friday, so once the morning fog burns off, outdoor plans should be in good shape.
