San Jose is headed for a warm one today, with inland highs topping out in the mid 80s while the Bay and Pacific coastlines grapple with higher-than-normal tides and rough surf. Morning low clouds should clear for inland neighborhoods by late morning, but bayshore and oceanfront areas will want to keep an eye on late-night saltwater surges and sneaker waves through the middle of the week.
Coastal Hazards At Night
Overnight high tides stacked on top of a long-period southerly swell are expected to bring minor coastal flooding and hazardous beach conditions through Thursday morning. Forecasters expect peak tides to run about 1.7 feet above normal and are warning about sneaker waves and strong rip currents that can quickly sweep people and belongings into the water. The most problematic late-night tides are forecast around 12:56 AM tomorrow, and again near 1:51 AM on Thursday.

Afternoon Heat Inland
Inland spots, including San Jose, are expected to climb to about 86°F this afternoon, with only a modest cooling trend tomorrow. Some interior valleys may run even hotter. Forecasters are calling this a Minor to locally Moderate heat risk for sensitive groups, so it is a good day to skip heavy exertion during the hottest hours and stay hydrated. For anyone without air conditioning, the county keeps a running list of libraries and designated cooling centers. Locations and hours are posted by the Santa Clara County Office of Emergency Management.
What Residents Should Do
For people in low-lying bayshore neighborhoods, move vehicles and ground-level belongings to higher spots before those late-night high tides roll in, and obey all barricades. Do not drive through standing water. Along the coast, stay well back from the surfline, never turn your back on the ocean, and swim only near lifeguarded beaches.
Inland, try to shift outdoor chores to the cooler morning or evening hours, keep water handy when you are outside, and check on elderly or medically vulnerable neighbors who might struggle with the heat.
