Swell Summary
Two moderate, long-period NW and NNW swells moving through the waters will keep surf heights elevated along N and W facing shores through Saturday. Surf along N and W facing shores will slowly trend down on Sunday. A hurricane force low E of Japan will bring another round of moderate, long-period NW (330 deg) swell into the islands towards the middle of next week building surf heights along N and W facing shores. This next long-period swell may possibly reach low-end High Surf Advisory levels Wednesday into Thursday.
A series of small, medium- to long-period S to SW swells will continue to filter into the area through the weekend keeping surf along S facing shores from going flat. Short-period surf along E facing shores increases slightly on Saturday due to the stronger trades, then trends down slightly Sunday through early next week.
