San Jose rolled in today, under clear skies and cool mid-50s, with temperatures on track to climb into the low to mid-80s this afternoon. Overnight lows are set to dip back into the upper 50s, and most inland neighborhoods should break out into sunshine by late morning. In other words, the long holiday weekend is kicking off mild and mostly dry across the South Bay.
Morning Fog, Sunny Afternoons
The marine layer will cling to the coast in the early hours before retreating back to the shoreline each afternoon, clearing the way for inland areas to warm into the low to mid 80s. The National Weather Service is calling for highs near 84°F today and similar numbers on Saturday. Winds stay on the tame side, running from the southwest at 1 to 8 mph and turning northwest over inland spots later in the day.
Independence Day And Weekend Outlook
Tomorrow is expected to be mostly sunny with a high around 84°F and a nighttime low near 58°F. Next Sunday and Monday should trend a bit cooler as a weak shortwave brings a stronger marine influence. Forecasters are also eyeing a more noticeable warmup by midweek, with a few inland locations tagged for a possible Moderate (orange) HeatRisk later in the week. If you are planning barbecues, park time or fireworks viewing, think layers for coastal evenings and plenty of water for inland outings.
Boaters, Beachgoers And Commuters
Out on the water, a Small Craft Advisory is in effect for the northern outer waters from Point Arena to Point Reyes through 9 AM tomorrow, so mariners and anyone heading toward the north coast should take it seriously. On land, low clouds and patchy valley fog could knock down visibility for early commuters, but conditions on most roads and at terminals should improve by mid-morning. If your plans involve the ocean, stick to lifeguarded beaches and be ready for a sharp drop in temperatures near the water.
How To Stay Comfortable
To ride out the holiday weather in comfort, hydrate, save heavy outdoor labor for the cooler morning hours and keep a light jacket handy for coastal evenings and fireworks shows. If you or someone you look after is sensitive to heat, keep an eye on conditions as midweek approaches, when inland highs may climb, and know where local cooling resources are available if needed. For the latest watches, warnings, and short-term updates, check the National Weather Service before heading out.
