San Jose woke up under a gray blanket of fog and mist around Mineta San Jose International Airport, with temperatures stuck in the low 50s and visibility reduced in low-lying neighborhoods. The marine layer is expected to thin by late morning, giving way to mostly sunny skies and a high near 68°F this afternoon. Along the coast, though, ocean conditions remain dangerous even as inland spots warm up.
Foggy Mornings, Sunny Afternoons
Patchy fog should hang on in some valley pockets through about 9 AM, then mix out as the sun gets to work. Inland neighborhoods will see the warmest readings later in the day. Northwest breezes will stay on the light side, generally 1–8 mph, so it will feel calm while temperatures climb into the upper 60s. If you are heading out, plan for a cool, damp start and a much brighter finish.
Coastal Hazards
Pacific Coast beaches are under a High Surf Advisory through 9 PM. Saturday, with breaking waves in the 17–22 foot range and an elevated risk of sneaker waves and strong rip currents, according to the National Weather Service. Even on a sunny afternoon, large breaking waves can appear without warning, so stay off jetties and rocks and remain out of the water.
Commuter Note
Drivers can expect slower-than-usual starts, as fog settles into low-lying areas and along creek crossings. Use low beams, give yourself extra stopping distance, and allow some bonus travel time this morning. Conditions should improve by midmorning as skies clear and temperatures rise.
Looking Ahead
A weak trough could bring a 20–40% chance of light rain to parts of the North Bay Sunday night, with better chances of measurable showers by midweek, as noted in recent Hoodline coverage of the cooler, wetter pattern. For now, expect a mostly dry stretch with pockets of morning fog before the weather turns cooler and wetter next week.
