San Jose rolled in today, under a low gray lid, with damp air, mid 50s on the thermometer, and clouds pressed tight along the bay. Most inland neighborhoods are expected to shake off the gloom by late morning and warm into the upper 70s, while spots right along the shoreline stay cooler and misty a bit longer. It is a brief cooldown compared with the warmer pattern earlier in the week, but by afternoon, much of the valley should be back in the sun with northwest breezes kicking in.
Afternoon Winds Pick Up
Northwest winds start off light, then build to around 1 to 10 mph this afternoon, with gusts reaching about 18 to 22 mph in wind-prone areas, especially near hill gaps and along the bayfront. Those gusts will put a chill on the waterfront even as inland neighborhoods feel pleasantly warm. Boaters and cyclists may want to plan for a choppier, windier late day, according to NWS San Francisco.
Foggy Mornings, Sunny Afternoons
The marine layer is running deeper this morning, roughly 1,000 to 1,500 feet, so low clouds and patches of fog will linger near the bay and along creeks before they burn off inland by mid to late morning. The immediate coast could squeeze out a little light mist or drizzle through the morning while inland areas flip quickly to sunshine and faster warming. This timing is a shift from the warmer outlook earlier in the week; see how San Jose sizzled toward 90 for comparison.
Week Ahead: Cooler Then Warmer
A slow cooldown holds through midweek, with Wednesday expected to be the coolest day, topping out in the low 70s with a breeze. After that, a warmer, drier pattern moves back in. Highs climb into the low to mid 80s by Thursday and Friday, and interior valleys could push into the upper 80s, close to 88°F, by Monday. Forecasters continue to flag a trend toward warmer, drier weather late this week and into next week, according to the NWS in San Francisco.
On The Water And Commute Notes
Coastal boaters should keep an eye on marine advisories, as small-craft conditions are possible in parts of the outer waters this afternoon and seas are expected to build later in the week. Drivers will mainly feel the impact in the morning, where fog and low clouds could slow the commute. Plan on extra time near bay bridges and shoreline approaches. If your plans land on Thursday or later, look for warmer, sunnier afternoons inland with a lighter marine influence.
