Beach Hazards Statement issued November 29 at 10:48PM PST until December 2 at 8:00AM PST by NWS Eureka CA
Effective: Sat November 29, 2025, 10:48 PM
Expires: Sun November 30, 2025, 7:00 AM
* WHAT...Increased threat of sneaker waves expected. A very long period swell rapidly building Monday will make surf on area beaches particularly high and unexpected even if seas otherwise seem calm. * WHERE...Coastal Del Norte, Northern Humboldt Coast, Southwestern Humboldt and Mendocino Coasts. * WHEN...From Monday morning through Tuesday morning. . * 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.
