High Surf Advisory issued January 8 at 12:51AM PST until January 8 at 4:00PM PST by NWS Portland OR

Effective: Thu January 8, 2026, 12:51 AM
Expires: Thu January 8, 2026, 4:00 PM

* WHAT...Large waves and hazardous surf conditions. Breakers up to 25 feet. * WHERE...North and Central Coast of Oregon, and South Washington Coast. * WHEN...Until 4 PM PST this afternoon. * IMPACTS...Destructive waves may wash over beaches, jetties, and other structures unexpectedly. People can be swept off rocks and jetties and drown while observing high surf. Minor beach erosion may damage coastal properties and buildings. Higher than normal water run-up is expected on beaches and low-lying shoreline. * ADDITIONAL DETAILS...The largest waves are expected to occur through 10 AM Thursday.

A High Surf Advisory means that high surf will affect beaches, producing rip currents, sneaker waves and beach erosion. Stay well back from the water's edge and be alert for exceptionally high waves. Keep away from large logs on the beach. Water running up on the beach can easily lift or roll logs which can injure or kill someone caught in their path.

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.
