A large south swell from Hurricane Marie will move into the region Friday night and Saturday, peaking Sunday into Monday, before gradually diminishing Tuesday. This will result in elevated to high surf and strong rip and longshore currents at majority of beaches. Additionally, waves will occasionally run much farther up the beach than expected, especially during increasing and evening high tides.
For south and southwest-facing beaches, expecting high surf 6-10 feet. This includes Orange County and north San Diego County beaches. For west-facing beaches, expecting elevated surf 4-7 feet. This includes most of southern San Diego County beaches.
High surf combined with high astronomical tides 6 to about 6.5 feet will lead to tidal overflow and coastal flooding Saturday through Tuesday during evening high tides, especially for those south and southwest-facing beaches as well as low-lying, typically impacted areas.
