San Jose starts the day cool and clear, with temperatures around 59°F at Mineta San José International Airport, but the chill will not last. Sunshine is set to drive inland highs into the mid‑80s today as the morning marine layer burns off inland by midmorning. Neighborhoods along the bay will hang onto the cooler, cloudy feel a bit longer before they brighten up.
Afternoon Winds Pick Up
By afternoon, winds turn west‑northwest and generally run around 0 to 9 mph, with slightly stronger gusts near hill gaps and along the bayfront. The hottest stretch of the day should land between about 2 PM and 4 PM, when temperatures top out near 86°F, then slide back into the mid‑50s overnight.
Heat And Fire Concerns
The National Weather Service is calling for highs near 86°F today and near 88°F tomorrow, with dry inland conditions lingering through midweek. That warm, dry setup has raised elevated fire‑weather concerns for the interior hills, and local agencies are urging extra caution. The Santa Clara County Fire Department is monitoring conditions and reminds residents to avoid outdoor burning and to secure anything that could spark a fire.
Weekend Outlook
By Friday, the marine layer deepens and starts to knock temperatures back a bit, setting up daytime highs in the upper 70s by Saturday, May 23, and next Sunday, May 24. Patchy fog is possible before about 7 AM next Sunday and Monday. Afternoons should stay mostly sunny, but plan on cooler, marine‑influenced mornings through the holiday.
Plan Ahead
Morning commuters should be ready for reduced visibility in pockets of fog and build in a little extra time. The warmest, sunniest window will be early to midafternoon, so that is when outdoor activities will feel hottest. Keep water handy if you are outside, skip recreational burning in dry, breezy spots, and boaters should check local marine notices before heading out.
