Eureka, CA – A sudden surge of sneaker waves could catch beachgoers off guard along California’s Northwest coast Saturday afternoon, with the highest risk expected between 1 and 6 p.m. Waves may appear calm before unexpectedly rushing high up the sand, posing a serious danger to anyone near the shoreline.
According to the National Weather Service in Eureka, a mid-period westerly swell is driving the alert, bringing moderate risk for these fast-moving, powerful waves from Humboldt Bay to Crescent City. Sneaker waves often strike without warning, sometimes after long stretches of calm surf. Officials warn they can knock people down or pull them into the ocean with little time to react.
Residents and visitors are urged to stay well back from the waterline, keep dogs leashed, and avoid climbing on rocks or logs near the surf. Emergency responders emphasize never turning your back on the ocean, even if conditions appear calm.
Beach hazards remain in effect through early Saturday evening, with additional alerts possible if wave energy increases. Stay tuned to local advisories and check conditions before heading to the shore.
