San Jose woke up under a gray blanket this morning, with clouds and cool air parked over the valley. Temperatures hovered near 54°F at Mineta San Jose International Airport, and a light mist left some neighborhood streets a bit slick. Northwest winds are already on the move at roughly 15–17 mph, tugging at trees as a very narrow band of low-level moisture slides through. Conditions are expected to brighten later in the morning as this front passes.
Cold Front Brings Quick Drizzle, Then Sunshine
A dry cold front will sweep across the Bay Area this morning, squeezing out a few light sprinkles or drizzle for commuters before skies flip to mostly sunny with a high near 65°F. The front should clear the region by late morning, with that clearing spreading inland soon after. Behind it, northwest breezes will steadily build through the afternoon.
Afternoon Winds Ready To Flex
By this afternoon, northwest winds in the valley should run around 10–15 mph, with gusts pushing up to roughly 25 mph. Exposed ridges, bridge approaches and coastal neighborhoods will feel even punchier. Drivers of high-profile vehicles and cyclists should be ready for sudden gusts, especially on the peninsula and along open highway stretches. If you are running errands or taking a bike across a bridge, expect the wind to occasionally nudge you around.
Weekend Warm-Up On Deck
Later in the week, the flow turns offshore, bringing in drier air and setting up a weekend warm-up. Afternoon temperatures are expected to climb into the 70s by Friday and stay pleasantly mild through Sunday. Nights will still dip into the low 40s under clear skies, so plan for crisp mornings even as afternoons feel more like spring. Rain chances stay close to zero into early next week.
Marine And Commute Notes
Small craft advisories and gusty conditions are in effect for parts of Monterey Bay and other offshore waters through Thursday, creating hazardous conditions for small boats and less experienced mariners. On land, expect possible minor transit slowdowns where wet roads and gusty pockets of wind show up together, with ferry approaches and exposed bridges particularly prone to blustery spells. For the latest advisory details and marine forecasts, see NWS Bay Area.
What To Do
Grab a light jacket and a small umbrella for the morning commute, and secure any loose patio furniture or trash cans if they are out in the open. If you are planning to take a boat out, cancel or postpone until after the advisory period and double-check official marine forecasts before you head for the dock.
