San Jose is starting Sunday with clear skies, calm winds and temperatures in the low 50s, but the afternoon will feel more like late summer than late October. The city should reach about 74 degrees under mostly sunny skies, with no rain expected and only a light northwest breeze.
How Sunday’s High Compares With October Norms
A high near 74 degrees is typical for the date by San Jose Airport’s climate benchmark: according to National Weather Service climate records, the normal high for Oct. 25 is 74 degrees. The record high for the date is 91, set in 2003.
Sunday is likely to be the warmest day in the week-ahead forecast. Highs are expected to be in the middle to upper 60s Monday and lower to middle 60s Tuesday and Wednesday, with morning fog and brisker afternoon winds also in the outlook. The listed precipitation chances are later in the week.
Early-Week Highs Settle Near 70
Monday starts with patchy fog before 8 a.m., followed by mostly sunny skies and a high in the middle to upper 60s. Northwest winds could gust as high as 20 mph, making the afternoon feel noticeably cooler than Sunday.
That cooler pattern holds Tuesday and Wednesday, when highs should stay in the lower to middle 60s, according to the National Weather Service. Morning fog is possible Wednesday.
Late-Week Rain Chances Remain Low
Thursday looks overcast, with a 2% chance of precipitation and a high near 68. Friday is forecast to reach near 69, with a 0% chance of precipitation.
Halloween falls on Saturday. The forecast details here give precipitation chances for Thursday and Friday, but no precipitation forecast for Saturday. That differs from Hoodline's previous forecast, which had called for a warmer start to the week.
A Separate Concern Along the Shoreline
San Jose is expected to stay dry for now. Separately, the National Weather Service has warned of minor coastal flooding around Bayshore locations along San Pablo Bay, San Francisco Bay and Monterey Bay during high tides. Advisories are expected to continue through Thursday, so low-lying shoreline areas are the focus of the regional warning.
