San Jose is in for a quick shot of early April heat, with a sunny warm-up set to follow a blustery morning today. As of 5:35 AM PDT, Mineta San José International Airport (KSJC) was clear, with temperatures around 46°F. Forecasters expect highs near 77°F today, then a jump into the mid 80s tomorrow and Sunday for inland neighborhoods.
Morning Gusts And The Commute
Offshore pressure will kick up moderate to strong northwest winds through midday Friday, with sustained speeds of 7 to 15 mph and gusts likely reaching 18 to 20 mph in exposed spots. According to the National Weather Service, mountain wave activity could shove some of those stronger gusts down into valley corridors during the morning commute. Cyclists and drivers in high-profile vehicles should take it slow, and anyone with lightweight patio furniture should secure it ahead of time.
Weekend Temperatures And Where It Will Feel Hottest
Temperatures will climb in a hurry. A high near 77°F is forecast for today; tomorrow, it is expected to reach around 85°F; and on Sunday, April 5, near 86°F. The warmest readings will be away from the immediate coast. Inland spots like East San Jose and the Santa Clara Valley are in line for the biggest jump, while coastal areas stay much cooler thanks to the ocean influence and a likely onshore return on Sunday. Overall, many neighborhoods will run roughly 10 to 15°F above what is typical for early April.
Coastal Boaters And Early-Morning Fog
Out on the water, Small Craft Advisories are in play. The advisory from Pigeon Point to Point Pinos lasts until this morning, while waters from Point Arena to Point Reyes remain under advisories into early tomorrow. Looking ahead, patchy fog may develop late Monday night into Tuesday morning, April 6 to 7, and there is a small chance of light rain from Tuesday night into Wednesday, April 7 to 8. For full details and the latest updates, check the National Weather Service.
What To Do And When
If you are planning to be outside, aim for late morning or early evening to dodge the windiest hours and the hottest sun. Carry water if you will be active during the warm afternoons tomorrow and Sunday. Boaters should double-check local forecasts and be ready to postpone launches if conditions stay choppy, and property owners will want to tie down loose items before Friday morning gusts arrive. There is no heat advisory in effect for the South Bay, but the warm spell is notable, so it is worth keeping an eye on the forecast if you have sensitive outdoor events scheduled this weekend.
