A high surf advisory remains in effect as previous swells continues to move through the area. We anticipated high surf warning impacts yesterday and today, but thankfully swells weren`t as strong as last week when ocean debris and extremely high surfs were observed. Wave heights will gradually diminish through Wednesday, before completely subsiding to 5 to 7 feet Thursday. Rough conditions may briefly diminish Thursday, however, east winds building Friday may produce rough seas once again.
