San Jose rolled into Sunday, under a blanket of low clouds, with temperatures hovering near 55°F at Mineta San Jose International Airport. A light onshore breeze is keeping the marine layer pinned closer to the coast this morning, while inland neighborhoods are expected to shake off the gray for partly sunny skies and a high near 71°F this afternoon. If you are eyeing the shoreline, pack an extra layer - the coast will feel noticeably cooler than the valley.
Foggy Mornings, Sunny Afternoons
Low clouds and patchy valley fog are expected to hang around through midmorning before breaking up inland by midday. According to the National Weather Service, west-southwest winds will stay on the gentle side at about 2 to 10 mph, so the warmup later in the day comes mainly from clearing skies rather than any big wind shift. We covered this same marine-layer setup in our weekend outlook, and today's forecast mostly tightens the timing on when the fog gives way to sun.
Coastal Hazards This Weekend
A Beach Hazards Statement remains in effect for Pacific coast beaches through 11 p.m. Sunday, with a long-period northwest swell raising the risk of sneaker waves and strong rip currents. Local coverage has been underscoring the warning; see the CBS San Francisco report for details. Even on stretches of sand that look calm, forecasters are urging beachgoers to watch the waves for 20 minutes before heading toward the water and to never turn their back on the ocean.
Early-Week Rain Chance, Then A Warm Push
According to the National Weather Service, there is a slight chance of light rain late Monday night into early Tuesday, overnight May 4-5, mainly over the North Bay and East Bay. Any rain that does fall is expected to be light. After that, high pressure starts to build and temperatures climb, with highs around 77°F on Wednesday, near 82°F on Thursday, May 7, and heading into the low to mid 80s by the weekend. Expect patchy morning fog through midweek followed by sunnier, warmer afternoons inland. Forecasters recommend checking for updates before locking in travel or outdoor plans, since small shifts in the models could nudge where any light showers decide to land.
