Swell Summary

Surf along exposed north and west facing shores will trend up today as a new, north-northwest swell arrives and builds down the island chain. This swell will peak tonight, then slowly lower Wednesday through Thursday. A larger north-northwest swell arriving Thursday night may near the advisory level Friday through Friday night as it peaks. This swell will gradually ease over the weekend. Surf along south facing shores will rise by Wednesday as a long-period south swell arrives and moves through. Surf associated with this swell should peak around Thursday before fading into the weekend. Surf along east facing shores will remain small and choppy each day due to the local trade winds.
