San Jose rolled in today under a blanket of low morning clouds and a mild 64°F at San Jose International Airport, but the cool start is not sticking around for long. Skies are expected to stay mostly cloudy through the day with a high near 87°F, and inland neighborhoods are on track to warm into the low 90s by midweek.
Week Ahead: Showers, Thunder Risk and Tides
Monsoonal moisture will drift into the Bay Area from today until tomorrow, setting the stage for scattered mid- and upper-level showers. There is also a low but notable chance of high-based thunderstorms that could spark lightning with very little rain and brief bursts of gusty outflow winds.
Out at the coast, the ocean is quietly doing its own thing. High tides will run higher than usual this week, thanks to a perigean spring tide tomorrow paired with a new moon on Tuesday. That combo bumps up the odds of minor inundation along low-lying shorelines. For detailed timing, water levels and any active advisories, check the National Weather Service.
Coastal Flood Advisory Through Thursday, July 16, 2026
A Coastal Flood Advisory is in effect through Thursday. Some bayshore gauges are already showing high tides running as much as 1.7 feet above normal, which is enough to produce minor flooding of parking lots, parks and low-lying roads around peak tides.
Residents and visitors are urged to move vehicles and valuables out of low-lying bayside lots ahead of late-night high tides and to be ready for isolated closures near the shoreline. Lifeguards and local public works crews may post temporary beach or access closures during the highest tides and during periods of rough surf.
Heat Safety And Cooling Centers
Away from the immediate coast, interior Santa Clara Valley neighborhoods will trend warmer through the week, with highs near 90°F tomorrow and into the low 90s Tuesday and Wednesday. A few far-interior spots could flirt with 100°F.
For anyone sensitive to heat or living without air conditioning, Santa Clara County maintains a list of cooling centers and other heat-relief resources for residents. Locations and guidance are available through the Santa Clara County Office of Emergency Management.
Plan Ahead
If you are heading for the shoreline, give jetties a wide berth, stay well back from the surf and move cars out of bayside lots well before late-night high tides. Keep an eye out for any lifeguard postings or temporary road closures near the water.
For outdoor plans inland, aim for morning or evening hours, bring plenty of water and stay flexible. If a pop-up thunderstorm rolls through, be ready to pause activities and take brief shelter until it passes.
