San Jose woke up to a crisp but mostly clear start today, with the airport clocking in around 54°F before sunrise. From here, the weather story tilts decidedly springlike: a bright, warm stretch is lining up, with afternoon highs in the upper 70s to low 80s through the weekend, while the immediate coast stays a bit cooler.
Afternoon Winds And Marine Advisories
As the day wears on, the breeze will pick up some attitude. Winds around San Jose are expected to shift to the west-northwest and strengthen this afternoon, with sustained speeds of 8–13 mph and gusts in the low 20s by late afternoon.
Offshore and at higher elevations, things get gustier tomorrow, where ridgelines could see gusts around 30–40 mph. According to the National Weather Service, Small Craft Advisories and Gale Warnings are posted for parts of Monterey Bay and the outer coastal waters, with building seas and hazardous conditions expected into Thursday evening. Anyone thinking about a casual boat outing may want to leave the keys on the hook.
Weekend Warmth
Temperatures stay a bit above normal into the weekend, with valley highs holding in the upper 70s to low 80s while mornings stay on the cool side. This lines up with the warming trend we flagged earlier this month; see the earlier post for more context on how this pattern set up.
Afternoons should feel comfortably warm for outdoor plans. Coastal spots and low-lying valleys, though, can still expect patchy morning fog to sneak in before the sun takes over.
Next Week Rain Chance
Early next week, the pattern flips a bit as a deeper storm track noses in. That brings a slight chance of light rain Monday night, with higher odds into Tuesday, and daytime highs dropping back into the 60s by midweek. Ensemble guidance keeps totals on the lighter side for now, but forecast models are leaning toward at least some measurable light rain for parts of the Bay Area starting Monday into Tuesday, according to the National Weather Service.
If you have outdoor projects, this weekend is still the better window before those showers try to make a comeback.
For commuters, patchy morning fog could occasionally cut visibility near river crossings and freeway on-ramps, so low beams and a few extra minutes in the schedule are your friends. Mariners and small-boat operators should hold off on nonessential trips while advisories remain in place. And for residents on exposed ridgelines, now is the time to secure loose outdoor items before Thursday’s gusty offshore winds move in. Otherwise, it is a pleasant, sun-forward run of days, as long as you keep a light jacket handy for those cooler mornings.
