Eureka, California – A moderate sneaker wave risk will develop along the Northwest California coast beginning at 10 p.m. Thursday, creating dangerous beach conditions near US-101 and coastal communities.
According to the National Weather Service in Eureka, a large, long-period swell is expected to enter coastal waters Thursday night. The swell may increase the likelihood of sneaker waves—powerful surges that can suddenly run much farther up the beach than normal waves.
The Beach Hazard Statement is in effect from 10 p.m. Thursday (Feb. 13) through 4 a.m. Saturday (Feb. 14). Impacted areas include beaches in Humboldt and Del Norte counties, including stretches near Eureka, Arcata and Crescent City.
Sneaker waves can overtake individuals who are unaware, particularly those standing near the waterline, exploring tide pools or climbing on rocks, jetties and coastal outcroppings. Officials warn the waves can knock people off their feet and pull them into cold, turbulent water.
Beachgoers are advised to choose flatter beaches, avoid steep shorelines, and stay off rocks and jetties during the advisory period. The National Weather Service also stresses never turning your back on the ocean.
While the hazard primarily affects beaches rather than roadways, travelers along US-101 and State Route 255 near Humboldt Bay should use caution when stopping at coastal access points.
The risk is expected to diminish early Saturday as swell energy gradually subsides.
Residents and visitors are encouraged to monitor updated coastal forecasts at weather.gov/eureka before heading to the shoreline.
