Beach Hazards Statement issued May 1 at 4:37AM PDT until May 3 at 11:00PM PDT by NWS San Francisco CA

Effective: Fri May 1, 2026, 4:37 AM
Expires: Fri May 1, 2026, 3:00 PM

* WHAT...An incoming long-period northwesterly swell will increase the risk of sneaker waves and strong rip currents. * WHERE...Beaches along the Pacific Coast. * WHEN...From Saturday morning through Sunday evening. * IMPACTS...Dangerous swimming and surfing conditions and localized beach erosion can be expected. Sneaker waves can sweep across the shoreline without warning, pulling people into the sea from rocks, jetties and beaches.

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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
