Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A long-lived south swell will affect the islands during the next several days, keeping south shore surf above the summertime average. The surf is expected to peak below the High Surf Advisory threshold of 10 feet today through Friday, then gradually decline Saturday through Tuesday. A series of overlapping long-period south swells will give another sizable boost to south shore surf Wednesday through late next week.

North shore surf will remain tiny today and tonight, followed by a small reinforcing short-period north-northwest swell late Friday through the weekend. A small long period northwest swell will build Sunday night, giving north shore surf a boost early next week. Surf along east facing shores will be well below normal levels through the middle of next week.
