Low clouds and stratus were expected in inland valleys Monday before sunny conditions developed, with overnight conditions also expected. The gray start will give way to sunshine, but it is only the opening act for a sharp South Bay warmup later this week.
Fog Clears, Then Sun Takes Over
The National Weather Service expects stratus to persist through late morning before retreating and conditions improving, followed by inland highs ranging from the middle 70s to lower 80s. Typical diurnal onshore winds will develop, with gusts reaching 20 to 30 mph through gaps and passes and in the northern Salinas Valley, while the chance of rain is effectively zero.
South Bay Heat Builds Through Thursday
Tuesday marks the start of a warming trend. Wednesday and Thursday are expected to bring inland highs ranging from the middle 80s to middle 90s. Mornings should stay cool during the midweek warmup, but the afternoons may feel noticeably hot for anyone sensitive to heat. The week-ahead picture is now clearer than the previous Hoodline forecast, with the warmest stretch arriving squarely in the middle of the week.
Cooler By Friday
Friday should reverse the warming trend, with temperatures closer to seasonal averages, followed by temperatures near seasonal averages into the weekend. Sunday is expected to be mostly cloudy, with brighter breaks around midday and early afternoon. No local weather advisories are listed for San Jose, so the practical forecast is simple: fog early, sun later, and plenty of water during the midweek heat.
