San Jose is squeezing in one more classic spring stunner today, with clear skies, chilly sunrise temps in the low 40s, and a quick warm-up into the 70s by afternoon. Look for a high near 74°F today across much of the valley, with inland neighborhoods set to creep into the upper 70s tomorrow before the pattern flips again. Those noisy overnight offshore gusts along the ridges are already backing off, leaving most lower-elevation spots with just a light breeze while clouds start to stage their return late Sunday ahead of the next round of rain.
Afternoon Winds Ease
Blustery offshore winds that have been hammering higher terrain this week, including a 63 mph gust at Mount St. Helena yesterday, are expected to taper until today. By the afternoon, they will give way to much lighter northwest winds in the 3 to 9 mph range. The National Weather Service notes that the strongest gusts have stayed confined to exposed ridgelines, while valley floors remain far calmer. If you have loose yard furniture, ladders, or gear on roofs and decks, keep everything secured until the lighter winds are firmly in place later today.
Weekend Outlook
Tomorrow is the warmest day in this brief sunny stretch, with inland highs near 79°F and plenty of blue sky, while coastal spots run noticeably cooler. Sunday starts off partly sunny but turns more unsettled as clouds thicken in the evening. Rain becomes likely after about 11 PM on Sunday and continues into next Monday, April 20. Next Monday looks cooler and wetter, with highs dropping into the upper 60s, and next Tuesday brings a chance of scattered showers and a few thunderstorms. If you are plotting barbecues, hikes, or any evening outdoor plans, aim for earlier in the weekend before the late-Sunday switch to wet weather.
What To Bring
For Friday and Saturday, pack for the split personality: sunscreen and sunglasses for the warm afternoons, plus a light jacket to fend off those chilly morning lows. By next Monday morning, be ready for wet roads, umbrellas, and slower commutes. Give yourself extra time and watch for slick patches during the early drive. Boaters should keep a close eye on updated marine forecasts from late Sunday into early next week, as winds shift southerly and seas turn choppier.
