Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A moderate, long period northwest swell will peak overnight and Saturday, producing surf well below High Surf Advisory levels on exposed north and west shores. A much larger northwest (320 degrees) swell will build Sunday and likely produce waves at or above High Surf Warning thresholds during the peak Sunday night and Monday. The swell will gradually decline Tuesday and Wednesday as a moderate north swell arrives.

Choppy east shore surf, already below seasonal average, will decline during the weekend as trades ease, and surf along east facing shores will remain small through the work week. Seasonably small surf will persist on southern shores, though a tiny bump will be possible during the middle of next week.
