San Jose is starting today on the mild side, with mostly clear skies and Mineta San José International Airport sitting near 70°F. Inland neighborhoods are on track to heat up into the low 90s this afternoon, while the coast and bayside spots hang back in the 60s and 70s. There is a small chance of brief, high-based showers, but most of that moisture will likely dry up before it ever hits the pavement.
Afternoon Heat And Hit-Or-Miss Showers
According to the National Weather Service, elevated tropical moisture will keep isolated, high-based showers in play today, even as inland highs climb to around 90–93°F. Meanwhile, bayside areas stay noticeably cooler. Northwest winds will stay on the lighter side today, with stronger onshore breezes returning by midweek and trimming temperatures closer to the shoreline.
Foggy Starts, Sunny Finishes
The marine layer is expected to rebuild overnight, dragging low clouds and patchy fog back into bayfront neighborhoods by Wednesday morning. If your commute hugs the waterfront, it might be worth giving yourself a little extra time to deal with the gray. Overnight lows remain mild, generally in the upper 50s near the water and mid 60s farther inland.
Boaters And Beachgoers
Conditions for small craft could turn hazardous later in the week as northwesterly winds pick up and a moderate southwesterly swell hangs around. Recreational boaters should check the latest marine forecast before heading out. Expect choppier seas and gusty onshore winds from Thursday into the weekend, which could throw a wrench into otherwise sunny plans on the water.
What To Expect
For everyday planning, layers are your best friend. Mornings near the bay may be cool and gray, only to give way to hot, dry afternoons inland.
