Beach Hazards Statement issued April 30 at 11:15PM PDT until May 3 at 11:00PM PDT by NWS Eureka CA

Effective: Thu April 30, 2026, 11:15 PM
Expires: Fri May 1, 2026, 11:15 PM

* WHAT...Increased threat of sneaker waves expected. * WHERE...Coastal Del Norte, Northern Coastal Humboldt, Southwestern Humboldt and Coastal Mendocino Counties. * WHEN...From Saturday evening through Sunday evening. . * IMPACTS...Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. These sneaker waves can also move large objects such as logs, crushing anyone caught underneath.

Don't be fooled by an ocean that looks calm. There can be 30 minutes of small waves before a sneaker wave strikes. Avoid rocks and jetties. Avoid steep beaches. Stay much farther back from the water and never turn your back on the ocean.

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.
