San Jose started the day on a bright note, waking up to clear skies and about 61°F. Sunshine will do the heavy lifting, sending local highs into the low 80s, with today’s high expected to land near 83°F. A steady midweek warm-up is already queued up, pushing inland spots into the upper 80s and low 90s by Friday. Nights will stay on the mild side, which means less overnight relief for folks in the hills and valleys.
Afternoon Winds Pick Up
Breezy onshore winds are set to kick in each afternoon and evening through early midweek, with west-northwest speeds around 1-10 mph and gusts up to 18 mph this afternoon. That is enough to nudge cyclists around and make high-profile vehicles wobble a bit on exposed routes. Expect choppier conditions nearshore and possible small-craft problems in the bay and Monterey Bay, so plan a little extra time if your commute involves bridges or other wide-open stretches.
Warming Through The Week
Temperatures edge up tomorrow, with a high near 86°F, then climb into the upper 80s to low 90s by Friday. Some inland spots are forecast to reach the low 90s. The National Weather Service is flagging a Moderate HeatRisk for many interior locations through the weekend and notes that pockets of Major to Extreme heat are possible for parts of the interior Central Coast. Officials are also pointing to very dry fuels, which could bump up fire danger inland. Try to schedule strenuous outdoor work for the morning or evening, and keep in mind that limited overnight cooling can make a multi-day heat wave feel especially uncomfortable. For the full technical outlook and any changing watches, check NWS Bay Area.
Coastlines Still Dangerous
A long-period southwesterly swell is keeping a Beach Hazards Statement in play through the end of the week, stirring up sneaker waves and strong rip currents at Pacific-facing beaches. Breaking sets up to 10-12 feet are possible at some south- and southwest-facing spots, including parts of Santa Cruz, Pacifica and Ocean Beach, and those bigger sets can surge far up the sand without warning. Stay well back from the waterline, skip the jetties and rocks, and only swim where lifeguards are on duty.
What To Watch And How To Stay Safe
If you are heading outside, favor mornings and evenings, carry water, and check the forecast quickly before you leave home. Keep an eye on neighbors, pets and anyone without air conditioning as temperatures ramp up. Boaters should pay close attention to small-craft advisories and be ready for rougher seas offshore, while beachgoers would be wise to avoid cliffs, jetties and unguarded stretches of shoreline. For the latest watches, warnings and hour-by-hour changes, consult the NWS Bay Area page and local county pages before heading out. When in doubt about surf or heat risks, it is safer to adjust plans than to test the limits.
