San Jose woke up today to a surprisingly cool start, with Mineta San José International sitting in the low 50s early this morning. Mostly sunny skies will nudge daytime highs toward about 75°F today, but the pattern turns fast. Inland highs climb into the upper 80s to around 90°F on Wednesday, June 10, and into the mid 90s by Thursday, June 11. Expect breezy afternoons and a brief chance of light coastal drizzle late tonight into early tomorrow.
Afternoon Winds Pick Up
Breezy onshore flow strengthens this afternoon, with south-southeast winds around 2 to 14 mph in the city and gusts into the mid 20s. Favored spots, including bayfronts, hill gaps, and wind funnels such as the Salinas Valley and Altamont Pass, may see stronger bursts up to 35 to 40 mph. Boaters should take note of Small Craft Advisories in parts of Monterey Bay and Gale Warnings for some outer waters this afternoon into the evening.
Heat Spike Midweek
By Wednesday, June 10, inland valleys will warm into the upper 80s to near 90°F, with many locations pushing into the low to mid 90s on Thursday, June 11. The warmest interior pockets still have a chance of reaching localized triple-digit readings. Dry, gusty north winds and poor overnight humidity recovery will elevate fire weather concerns across the interior North Bay mountains late Wednesday into Thursday. These trends and the forecast heat risk are outlined by the National Weather Service.
Stay Cool And Where To Go
If you are sensitive to heat, plan ahead. Take frequent shade and water breaks, avoid strenuous outdoor work during the hottest afternoon hours, and check on neighbors, children, and pets. The County maintains an up-to-date hot weather resource page and a list of cooling center for residents; see the Santa Clara County Office of Emergency Management for locations and hours.
