San Jose is starting Sunday with patchy fog and a final chance of a rain shower before 9 a.m., but the gray start should give way to sunshine. Temperatures will climb to about 66 degrees before slipping into the lower 60s during the afternoon, with light west-northwest winds adding a little autumn bite.
Fog And Showers Fade Sunday Morning
The morning commute could be damp in spots, though rainfall should remain light, with amounts across the broader area ranging from a trace to 0.25 inch. Skies are expected to clear quickly after the morning fog, setting up a mostly sunny afternoon for errands, parks and outdoor plans.
The latest forecast is a meaningful update from the Halloween outlook, which had focused on late-night showers and a cooler Sunday. The earlier Hoodline forecast called for a sunny rebound, and that part of the forecast is now arriving with a slightly warmer afternoon.
Monday Warms Up Before Another Rain Chance
Monday should be dry and warmer, with areas of fog before 8 a.m. followed by partly sunny skies and a high near 70 degrees. Monday night will stay mostly cloudy, with another round of patchy fog possible after 4 a.m. and a low around 47.
Tuesday brings the next unsettled stretch, with patchy fog early and a 40% chance of rain showers between roughly 10 a.m. and 4 p.m. San Jose could reach about 68 degrees, while rainfall is expected to remain light; the National Weather Service’s latest forecast discussion puts the highest totals farther north and keeps the South Bay on the drier side.
Sunny And Warmer Later This Week
Wednesday looks mostly sunny with a high near 69, followed by mostly cloudy skies and a high around 70 Thursday, then mostly sunny skies and a high around 73 Friday. The warmup peaks next Saturday, when San Jose could reach about 76 degrees under sunny skies.
Anyone heading toward the Bay shoreline or the coast should take separate advisories seriously: minor coastal flooding remains possible around vulnerable Bayshore locations through Sunday evening, and hazardous beach conditions are expected from late Sunday night through Tuesday evening. Those concerns do not apply broadly to inland San Jose, but they could affect waterfront roads, paths and beach plans.
