San Jose woke up clear and around 50°F this morning, and what feels like an extended spring stretch is already nudging inland highs into the upper 70s today. A much stronger warm-up is waiting in the wings next week. Nights will stay mild, with lows in the upper 40s, and there is no rain in the cards through the weekend.
This Afternoon And The Weekend
Mostly sunny skies and a light west-northwest breeze are expected to push temperatures into the upper 70s this afternoon. Tomorrow is on track to look much the same, while Sunday turns noticeably warmer. Patchy morning fog could form in low-lying spots before 8 a.m., but afternoons should be dry and clear. If you have outdoor errands or exercise planned, the cooler morning hours will be your best bet.
Heat Spike Next Week
Temperatures climb sharply next Sunday and become widespread early next week, with highs forecast near 90°F next Monday, and near 94°F next Tuesday, according to the National Weather Service. The NWS forecast discussion also notes that this pattern could produce daily record highs at several long-term sites and points to an elevated potential for small grass fires as offshore winds develop. Forecasters add that overnight lows will run warmer than normal, which means limited relief after sunset.
How To Stay Cool
If you or someone you care for does not have air conditioning, shift outdoor activity to the morning or evening, drink plenty of water, and plan errands for the cooler parts of the day. Local libraries and community centers often open as cooling centers during heat events, and the city has activated them during past heat spells.
On The Water And Fire Watch
Boaters should be ready for choppy seas and Small Craft Advisories at times along the coast, while the return of drier offshore winds next week raises the chance that cured grasses could contribute to small fires in vulnerable areas. Take extra care with grills, cigarettes, and campfires when you are outdoors, and check marine advisories before heading out. The National Weather Service maintains current marine and fire-weather details in its NWS forecast discussion.
