San Jose is waking up around 52 degrees under mostly clear skies Monday, but the easy-breezy weekend warmth is giving way to a cooler, foggier pattern. Patchy fog may linger until about 10 a.m. before sunshine takes over, with the afternoon topping out near 67 degrees.
Fog Burns Off, Winds Pick Up
Monday afternoon should stay dry and mostly sunny, though northwestern winds will build through the day. Gusts could reach 18 mph, especially later in the afternoon and evening, according to the National Weather Service.
Temperatures will fall quickly after sunset, with a low near 48 degrees Monday night and another round of patchy fog possible before Tuesday morning. Commuters should get a clearer ride after the fog lifts, but the breezier afternoon may be noticeable on exposed roads and open trails.
Cooler Week Ahead
Tuesday brings another mostly sunny afternoon with a high near 65, followed by Wednesday's modest rebound to about 68 degrees. Thursday should reach roughly 66, while Friday looks cooler again, with a high near 62.
Overnight lows will mostly settle in the mid-40s to upper 40s, and patchy fog could return during several morning commutes. The overall pattern is mild by Bay Area standards, but noticeably less summery than the weekend.
Rain Chance Arrives For Halloween Weekend
Rain chances begin to creep into the forecast Friday night, with a slight chance of light rain Saturday and Sunday. Halloween afternoon is expected to be partly sunny with a high near 61, while Sunday should reach about 62 under mostly sunny skies despite the lingering rain chance.
That forecast does not currently point to a washout, but outdoor plans may want a backup layer — and possibly a compact umbrella — as the week winds down.
High Tides Could Affect Shoreline Areas
A coastal flood advisory remains in effect through Thursday for vulnerable low-lying areas around San Francisco Bay, San Pablo Bay and Monterey Bay. The advisory is not aimed at most of inland San Jose, but people heading toward the shoreline should watch for minor flooding around high tide, isolated road impacts and higher water along beaches and tidal waterways.
