City lifeguard officials reported coastal flooding on San Diego beaches amid a 12-foot swell and a 6.4-foot high tide shortly before 8:30 a.m.
Officials in Coronado also closed several streets in Coronado because of the high tides. The paseo behind the Hotel del Coronado was temporarily closed between the jetty and Avenida Del Sol, according to the Coronado Police Department.
A National Weather Service coastal flood advisory is set to expire at noon, and a high surf advisory will end at 8 p.m. Surf of 6 to 10 feet with sets to 12 feet this morning are expected to lower to 4 to 8 feet this afternoon.
Weather service forecasters said the potentially damaging surf pounding the county's beaches this morning would lower as the day progresses. However, the surf and associated rip currents may lead to hazardous swimming conditions throughout the day.
