A southwest swell that drew some of its energy from former Hurricane Narda will produce hazardous surf along the San Diego County coastline from early Sunday to late Tuesday, producing rip currents strong enough to capsize small boats near shore, the National Weather Service said.

The surf will be strongest at south-facing beaches, generating 4- to 7-foot waves, with occasional sets to 8 feet at south and southwest-facing breaks.

“Rip currents can pull swimmers and surfers out to sea,” the weather service said in an advisory. “Waves can wash people off beaches and rocks, and capsize small boats nearshore.”

Sea surface temperatures will be in the 63- to 67-degree range.
