San Jose is waking up under clouds near 59 degrees today, but the gray start should give way to sunshine and a high around 75. The bigger change arrives after sunset, when a cooler, cloudier pattern settles in with foggy mornings and afternoon temperatures mostly in the low-to-mid 70s.

Sunshine Gives Way To A Breezier Finish

The National Weather Service expects sunny skies today, with south winds ranging from 2 to 12 mph and gusts up to 21 mph. Temperatures should peak near 75 before easing toward the low 70s late in the afternoon, while tonight turns mostly cloudy with a low near 57.

Foggy Mornings Arrive Tuesday

Patchy fog is possible between 7 and 8 AM tomorrow, before mostly sunny skies return, and the high reaches about 72. Wednesday through Friday follow the same basic script: fog or low clouds early, then brighter afternoons near 76 degrees, with overnight lows dipping into the mid-50s.

Dry, Mild Weather Holds Through Sunday

Rain chances in San Jose remain at or below 3% through next Sunday, and no weather alerts are listed for the city, so morning fog and low clouds—not wet weather—are the main story. Saturday should reach around 77 under mostly sunny skies, followed by mostly sunny skies next Sunday near 78.

For early commuters and walkers, a light layer will be useful tomorrow through Friday, especially before the sun breaks through. Afternoon conditions look comfortable for outdoor plans, though today's gustier breeze could turn loose napkins and lightweight patio decor into temporary neighborhood wildlife.
