Swell Summary

Strengthened trade winds and a north northeast swell will continue to support the High Surf Advisory (HSA) for exposed east-facing shoreline surf through Sunday. The next appreciable northwest swell is scheduled to pass around the islands Wednesday and Thursday. This moderate height, lower period northwest swell may push surf along north and west-facing shores to HSA levels Wednesday and Thursday. Periodic small, long period southwest to south swells emanating from gales south of New Zealand will produce a modest boost to mid week south-facing shore surf.
