San Jose is waking up to a cool Sunday morning, with breezy conditions giving the South Bay a distinctly active start. Sunday inland highs should range from the middle 70s to lower 80s before easing later in the day. Gusts may reach 24 mph, so patio umbrellas and lightweight outdoor decorations may need a little attention.

Sunny, Breezy Sunday

According to the National Weather Service, Sunday will remain dry with a negligible chance of rain and mostly clear skies after the early morning hours. Northwest winds will run between 8 and 14 mph, with stronger gusts continuing into the afternoon. Inland San Jose should be warmer than coastal neighborhoods, where patchy low clouds may linger or return overnight.

Warmer Temperatures Arrive Monday

Monday brings a noticeable warmup, with a high near 83 degrees. Tuesday through Thursday should see inland temperatures generally in the 80s, while Friday into the weekend may bring a slight warming trend. Regional overnight lows should be in the upper 40s to 50s, making early mornings much cooler than the afternoons.

Coastal Fog Could Return

The broader Bay Area forecast calls for the marine layer to rebuild Monday night into Tuesday, bringing some coastal fog or low clouds during the morning before they clear later in the day. San Jose, farther inland, may avoid the thickest of the gray, but travelers heading toward the bays or Pacific coast should expect a cooler start. The latest outlook updates Friday’s forecast with a clearer picture of the warmer, dry week ahead.
