Effective: Wed December 31, 2025, 12:21 PM
Expires: Thu January 1, 2026, 3:00 AM

* WHAT...Dangerous rip currents and breaking waves due to elevated surf expected. Minor coastal overflows possible due to abnormally high tides between 6.7 and 7.5 feet and gusty southerly winds. * WHERE...San Luis Obispo County Beaches and Santa Barbara County Central Coast Beaches. * WHEN...From late tonight through Sunday afternoon. * IMPACTS...Pooling of sea water is possible around high tide at beach and harbor areas that is uncommon with normal tidal ranges. Enhanced beach erosion is also possible. No significant damage is expected. There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. Waves can wash people off beaches and rocks, and capsize small boats nearshore. * ADDITIONAL DETAILS...Peak high tides are expected between 5 am and 9 am on New Years Day, shifting to between 7 am and 11 am by Sunday. There is a moderate chance for Coastal Flood Advisories and/or High Surf Advisories to be issued for this weekend as another storm system may generate strong winds accompanied by a larger swell.

Remain out of the water due to hazardous swimming conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions, stay off the rocks.

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.
