Swell Summary
Surf along south facing shores will remain elevated keeping levels near average through Saturday. A larger, moderate south swell is expected to build Sunday through early next week, bringing potentially High Surf Advisory level conditions Monday and Tuesday. As this swell slowly fades into the middle of next week, another moderate south swell is expected next Thursday. A small, medium-period west-northwest swell will gradually fade today into the weekend, causing surf along north- facing shores to drop to tiny by the weekend. East facing shores will remain choppy through Saturday and will gradually drop as trade winds ease. Energy from Tropical Storm Elida may reach the islands during the middle of next week bringing a slight boost for east facing shores.
