Swell Summary
Based upon the latest south swell moving through Samoa a few days ago, long period energy from this swell will begin arriving in our far offshore waters during the day today. South swell should begin building surf along south facing shores through the day, peaking surf to below surf advisory levels Sunday through Monday and then gradually lower through the middle of next week. Some south wrap may work is way around to more western facing shores, picking up west surf by another foot or so. Short period, choppy wind wave surf will hold steady through the weekend along eastern facing shores, then lower slightly early next week as trades weaken. Surf along north facing shores will remain just above flat through the weekend. A small, medium period northwest swell is forecast to move through during the first half of next week. This should provide a little boost in north shore surf.
