San Jose is starting Tuesday with a cool morning. Patchy stratus and moderate northwest boundary-layer winds are part of the regional weather pattern. The bigger shift is ahead, with cooler nights, recurring morning fog and only a slight chance of light rain for Halloween weekend.
Afternoon Sun Gives Way To Chilly Nights
Wednesday should warm slightly to near 68 degrees after patchy fog before 10 a.m., while Thursday reaches about 66. Friday's high is near 62. Overnight lows will remain in the mid-40s, so the evening costume strategy may involve a jacket instead of sheer optimism.
Halloween Looks Cool, Not Like A Washout
Saturday brings partly sunny skies and a high near 61. The chance of rain is just 15%, with any precipitation expected to be light. A slight rain chance continues Saturday night before Sunday reaches about 62 degrees, with mostly sunny skies and a lingering rain chance.
Coastal Flooding Remains A Shoreline Concern
Most of inland San Jose is not included in the coastal flooding concern, but people heading toward waterfront areas should stay alert. The National Weather Service says minor flooding is possible around low-lying Bayshore locations near San Pablo, San Francisco and Monterey bays during high tides through Friday.
The Forecast Is Trending Drier For The Weekend
The latest outlook is less threatening than the one described in Monday's Hoodline forecast, which flagged broader Halloween weekend rain chances. San Jose now has only a slight chance of light rain Saturday and a lingering rain chance Sunday, making layers and fog awareness more useful than planning for an all-day downpour.
