Today, San Jose woke up under cloudy skies and light showers sliding through parts of the South Bay, with Mineta San Jose International Airport clocking in around 63°F. The National Weather Service is calling for a cool, damp stretch through Thursday, with highs hovering near 67–70°F. Drivers can expect slick roads for both the morning and evening commutes, and cyclists should be ready for wet pavement and a few stray sprinkles.
What To Expect This Week
Light rain will come and go through Thursday, with the main system arriving midweek and the heaviest rainfall focused on coastal and mountain areas. The NWS Bay Area says mountain totals could reach 0.25–0.60 inches, valley locations 0.05–0.25 inches, and the Peninsula down to Santa Cruz around 0.10–0.35 inches, while many neighborhoods pick up less than a tenth of an inch today. Most showers should stay on the lighter side, but even modest rainfall can make streets slick during peak commute times.
Commute And Coastal Impacts
Brief visibility reductions are possible in heavier bursts, which means slower traffic on major routes and local arterials, so it is worth padding your schedule if you are driving during the today or tomorrow's rush hours. Boaters and anyone planning time on the water should be cautious, as seas trend choppier with fresh southwesterly breezes ahead of the front, followed by stronger northerly winds later this week. If you rely on buses or trains, keep an eye on transit schedules and service alerts to avoid any wet-weather surprises.
Late-Week Warm-Up
By Friday, an offshore ridge builds back in, and the forecast turns noticeably warmer and drier, with highs near the mid-70s on Friday and low 80s expected over the weekend. Forecasters also note that gusty offshore winds are possible in favored gaps and on hilltops, with gusts reaching 30–45 mph in exposed spots, so it is a good idea to secure loose outdoor items if you live on a ridge or near open terrain. After Thursday’s final showers, the shift should deliver a sunnier, more summer-like weekend.
Bottom line: carry a compact umbrella this week, allow extra travel time on wet roads, and tie down anything that could fly away before the late-week gusts arrive. For the latest conditions and any watches or advisories, check the NWS Bay Area and VTA service alerts.
