San Jose is starting today under a cloudy sky and around 61 degrees, but the morning gray is on borrowed time. Sunshine should take over quickly, sending temperatures to near 87 this afternoon before a cooler, cloudier pattern arrives late Thursday and Friday.

One More Warm Afternoon Before The Shift

Today will be sunny, with temperatures climbing through the 70s around midday and peaking near 87 in the afternoon. Northwest winds should stay manageable at roughly 2 to 10 mph, though the breeze may become more noticeable later in the day.

Tomorrow remains warm but turns mostly cloudy, with a high near 86 and an overnight low around 63. That is a sharper change from the low-80s stretch described in an earlier Hoodline forecast, especially with rain now appearing in the near-term outlook.

Friday Brings A Small Rain Chance

Friday will be cooler, with a high near 80 and a 20% chance of light rain before 11 a.m. The best chance for a few drops comes early, with partly sunny skies expected later in the day and a low around 58 Friday night.

Sunny Weekend, Foggy Mornings

Saturday looks sunny and comfortable, topping out near 78 degrees, while Sunday should bring patchy fog before 9 a.m. followed by sunshine and another high near 78. Overnight temperatures will fall into the mid-50s, so early-morning plans may call for a light jacket.

Monday stays mostly sunny and cooler, with a high near 73, and Tuesday should reach about 75 after patchy morning fog. The pattern offers a gradual step down from Wednesday's warmth rather than a sudden temperature plunge.

Dry Hills And Noticeable Afternoon Breezes

The National Weather Service says warm, very dry conditions will continue above 1,000 feet through Thursday, where fire-weather concerns remain elevated. Northwest winds will generally stay light in San Jose, but exposed hills, coastal areas, and regional gaps could see stronger afternoon gusts as the cooler pattern arrives.
