Big waves challenge surfers at Malibu, Calif., as a long-period, south swell moved into the Southern California Bight on Sunday, May 3, 2015. The National Weather Service said the swell, with a period of about 20 seconds, would translate to surf of 5 feet to 8 feet with local sets to 10 feet at favored south-facing beaches including Malibu.

NEWPORT BEACH, Calif. (AP) — Big surf kept rolling ashore Monday along south-facing sections of the Southern California coast after bodysurfers challenged the towering waves over the weekend and lifeguards were kept busy pulling people from the water.

The highest surf was expected Monday, with some sets reaching more than 12 feet along beaches in Orange and San Diego counties and 10 feet at Malibu and Zuma in Los Angeles County, the National Weather Service said.

Lifeguards at the Wedge in Newport Beach, a famous surf spot, reported 15-foot waves Monday afternoon. Six- to 8-foot waves were recorded at Santa Monica with slightly higher surf in Venice.

A high-surf advisory remained in effect through Tuesday.

Cloudy weather kept crowds at bay at Newport Beach, which saw 55,000 visitors over the weekend. Even so, more lifeguards were on duty Monday than usual because of the expected surf, said Newport Beach Chief Lifeguard Rob Williams.

The rough conditions extended north along the coast to San Luis Obispo County. Avalon, Port San Luis, San Simeon and Cayucos could see currents capable of dislodging moored vessels and docks, forecasters said.

“Inexperienced swimmers should definitely stay out of the water,” Seal Beach police Sgt. Ron LaVelle said.

Lifeguards pulled 17 people out of the water over the weekend off Newport Beach. It was the busiest weekend for lifeguards since March when 134 people were rescued during a weekend of big waves and warm weather.

The high tides have been caused by a Southern Hemisphere storm.

The conditions caused minor flooding Sunday night along beachfront homes in low-lying Seal Beach. Water washed up over the boardwalk, but there was no property damage.

Lifeguards were filling sandbags on Monday and planned to dig trenches to divert water from the lowest spots of the beach.
