Swell Summary
Southwest swell energy combined with a lingering southeast trade wind swell will likely maintain small surf along south facing shores through early next week. A small, medium-period north-northwest swell will likely cause a slight bump in surf along exposed north and west facing shores this weekend. In addition, a small north swell may arrive around Tuesday, followed by a modest north-northeast swell from Thursday into Friday. Moderate, rough surf will likely persist along east facing shores into early Sunday. The surf may lower slightly along east facing shores from late Sunday into Tuesday due to a slight weakening of the trade winds.
