NWS: High Surf on the Horizon

A high surf advisory will be in effect along Hermosa Beach and other parts of the Southern California coast, starting at 5 p.m. Wednesday, according to the National Weather Service in Los Angeles.

A strong storm system near New Zealand has produced large swells, which have crossed most of the Pacific Ocean on their way to the South Bay, the weather advisory said.

Those swells are expected to hit the local shoreline Wednesday night, and persist until Friday night. 

The swells will have a period of around 20 seconds—producing breaks reaching 11 feet at peak times. The weather advisory also warned that the swells could create a high risk for rip currents.

"The surf may cause hazards for anyone entering the water," the advisory said. "Producing rip currents and localized beach erosion."

The weather advisory was issued Tuesday.
