Coastal Conditions Remain Rough

For residents heading toward the coast, hazardous beach conditions remain a concern Monday evening, with sneaker waves, strong rip currents, and isolated breaking waves of 18 to 20 feet possible at favored break points. A Coastal Flood Advisory remains in effect for designated Bay Area shoreline locations through Tuesday at 3 p.m. Visitors should stay away from jetties, rocks, piers, and other waterside areas during high tides. The NWS coastal hazard notice gives the alert details.

The coastal alerts carry distinct risks: isolated breaking waves of 18 to 20 feet are possible at favored break points. The beach hazards statement continues through Monday evening; the coastal flood advisory runs through Tuesday at 3 p.m. Those alerts apply to designated coastal and bay-shore locations, rather than indicating flooding or surf hazards across San Jose. The NWS coastal hazard notice spells out the expected impacts and timing.
