Effective: Tue October 6, 2026, 1:27 AM
Expires: Tue October 6, 2026, 2:30 PM

* WHAT...For the Beach Hazards Statement, dangerous rip currents expected. For the Coastal Flood Advisory, minor coastal flooding expected. * WHERE...San Diego County Coastal Areas and Orange County Coastal Areas. * WHEN...For the Beach Hazards Statement, from this afternoon through Friday evening. For the Coastal Flood Advisory, from 6 AM Wednesday to 11 AM PDT Friday. * IMPACTS...Flooding of lots, parks, and roads with only isolated road closures expected. Minor coastal erosion is also expected. Additionally, elevated surf will lead to strong rip currents. * ADDITIONAL DETAILS...Elevated surf of 3-5 feet, with sets to 6 feet, on south- and southwest-facing beaches. High tides are expected to peak between 6.5 and 7.0 feet during the mornings and evenings.

A beach hazards statement for elevated surf means that waves will be high enough to cause danger to inexperienced swimmers in the water. Elevated surf also frequently results in strong rip currents which can drag people away from the shore and possibly result in drowning. Always swim near a lifeguard. A Coastal Flood Advisory indicates that tides and elevated surf will combine to generate localized flooding of low areas along the shore.

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.
