A high surf advisory has been issued for San Diego County until Wednesday afternoon, according to the National Weather Service.
Wave height up to 8 feet is expected today, with occasional 9-foot waves at west-facing beaches.
Larger wave sets may cause water to flow over jetties and coastal flooding, warned NWS. Swimmers are also urged to watch out for strong rip currents.
Surfers should avoid beaches south of Carnation Avenue, as a water contamination closure has been issued.
The surf advisory is in effect until 4 p.m. on Wednesday.
