Beach Hazards Statement issued January 31 at 2:18PM PST until February 2 at 4:00PM PST by NWS Portland OR

Effective: Sat January 31, 2026, 2:18 PM
Expires: Mon February 2, 2026, 4:00 PM

* WHAT...Sneaker waves possible. * WHERE...North and Central Coast of Oregon, and South Washington Coast. * WHEN...Through Monday afternoon. * IMPACTS...Waves can run up significantly farther on a beach than normal, including over rocks and jetties. Sneaker waves can suddenly knock people off of their feet and quickly pull them into the frigid ocean which may lead to serious injury or drowning. * ADDITIONAL DETAILS...Keep children and pets away from the surf zone. Keep off of jetties, rocks and logs near the surf zone. If you see someone swept into the sea do not swim in after them. Call 911 and keep an eye on them until help arrives.

Remain out of the water to avoid hazardous swimming conditions.

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.
