Sunday is expected to be sunny, and the South Bay is about to trade its light-jacket weather for a midweek heat spike. Sunday's high should be about 76 degrees before warming to 83 on Labor Day. Tuesday's high is forecast near 87 degrees.

Sunny Sunday, Noticeably Breezy By Afternoon

Sunday will be sunny, with a high near 76 degrees. Sunday afternoon could bring northwest wind gusts of about 22 mph.

Overnight conditions are expected to be mostly clear. The latest outlook is a sharper warmup than the weekend forecast covered by Hoodline on Saturday.

Labor Day Starts The Warmup

Monday will be sunny, with a forecast high near 83 degrees and relatively light northwest winds. That makes for favorable conditions around San Jose, though the overnight low will be around 60, so layers may remain useful before the afternoon heat arrives.

Wednesday Brings Midweek Heat

Tuesday's high is forecast near 87 degrees. Later-week temperatures are not specified here.

Wednesday-night lows are not specified here, and Friday and Saturday temperatures are not specified here. Light rain could occur across parts of the region from Tuesday through Thursday.

Coastal Beach Hazards Continue Through Monday

People heading from the South Bay to the coast should take a separate warning seriously: the National Weather Service says long-period swell could produce sneaker waves, strong rip currents and breaking waves up to 10 feet. The National Weather Service advises avoiding the water unless you are an expert swimmer and never turning your back on the ocean.

If a rip current catches you, swim parallel to the shoreline until the pull eases, then head back toward the beach. Inland plans look much calmer, but the combination of sunshine and rising temperatures will make water, shade and lighter afternoon activity increasingly useful by midweek.
