Beach Hazards Statement BEACH HAZARDS STATEMENT  
Los Angeles County

  Effective: Sat, 5/16 4:14am Severity:  Moderate 
  Updated: May 16, 2026 7:15 am Urgency: Expected
  Expires: Sat, 5/16 3:00pm Certainty: Likely

Areas Affected: San Francisco - Coastal North Bay Including Point Reyes National Seashore - San Francisco Peninsula Coast - Southern Monterey Bay and Big Sur Coast
 
Alert Details:
* WHAT...Strong northerly winds will generate very rough
conditions at area beaches along with strong rip and longshore
currents.

* WHERE...Greatest impacts will be along west facing beaches of
the Pacific coastline.

* WHEN...Through Monday morning.

* IMPACTS...Dangerous wind and wave conditions will impact
beaches and water activities such as swimming, surfing,
boating, and tide pooling. Rough seas can sweep up the beach
and over rocks and jetties, pulling people into a cold
turbulent ocean. Rip currents will be stronger than normal and
long shore currents can move people and items in the water
quickly away from the point of entry. Local beach and cliff
erosion is possible. Water temperatures will also cool rapidly
due to strong upwelling conditions during this time. Large
tidal swings can cutoff access to beach walkers.

Information:
Stay off of jetties, piers, rocks, and other waterside
infrastructure. Remain out of the water to avoid hazardous surf
and NEVER turn your back on the ocean. Monitor local weather,
surf and tide forecasts at www.weather.gov/mtr.
