San Jose woke up under a blanket of low clouds today with temperatures stuck in the mid-50s. The gray start will not last, though, as skies clear into a sunny afternoon with a seasonable high near 80°F. After sunset, expect the marine layer to creep back in and tonight’s low to drop to around 52°F.

Foggy Mornings, Sunny Afternoons

A shallow marine layer, roughly 1,500 to 2,000 feet deep, has pushed inland from the coast and is keeping low clouds and patchy fog in place across the North Bay, Monterey Bay region and the Salinas Valley through mid to late morning. Inland neighborhoods should see the clouds burn off by midday, with highs in the upper 70s to around 80°F, while shoreline areas stay cooler and misty longer. Onshore breezes will develop this afternoon with gusts up to about 20 mph in favored gaps and passes, and a Small Craft Advisory is in effect for parts of the outer waters early this morning. Forecasters also expect a cold front to sweep through next Tuesday, May 26, bringing a modest cooldown and only a slight chance of light coastal showers, according to NWS San Francisco.

Afternoon Winds Pick Up

Onshore winds will strengthen during the afternoon and evening, making the waterfront feel several degrees cooler even as the valley warms. Gusty pockets near bay bridges and hill gaps could reach 15 to 20 mph, so cyclists and shoreline visitors may want to brace for brisk conditions.

Boaters And Commuters

Boaters should heed advisories for the outer waters this morning and check local notices before heading out, as conditions are expected to calm later in the day. Morning commuters along bayfront routes and through low-lying creek corridors should plan for patchy fog and reduced visibility during the early commute, with most roads clearing by late morning.

Memorial Day Weekend Outlook

Memorial Day, next Monday, May 25, will start with some patchy fog, then turn mostly sunny and mild with highs near 75°F across much of the valley. Next Tuesday, May 26, the front should bring slightly cooler and breezier conditions. Widespread measurable rain is not expected, although light coastal drizzle or brief showers could pop up in a few spots.
