Swell Summary
A small, medium period north swell is moving through the islands. This will keep small surf across north-facing shores through Sunday. However, the arrival of a new, moderate long period north (350 degree) swell late Sunday night or early Monday morning will bring advisory level surf along north-facing shores. This swell will peak Monday evening and then slowly decline through mid week.
A small, long period south (180 degree) reinforcement continues to hold, producing waist to chest-high surf along south-facing shores. South shore surf will slowly decrease through early next week as this reinforcement fades. Surf along west-facing shores will remain elevated, influenced by both the north and south swell wrap. East-facing shore wind wave chop will remain relatively small under the relatively weak trade wind regime.
