Forecast for Big Island Leeward

Swell Summary

Moderate to locally strong trade winds will keep east shore surf close to seasonal levels through Saturday. Surf will then lower below normal Sunday through the middle of next week as the trade winds diminish upstream of the island chain.

South shore surf will remain small through Friday, then trend up to slightly above normal levels Saturday through Monday as a new moderate size south swell moves through. Surf will then lower back to small levels Tuesday through Thursday.

A series of small northwest swells will move through the area today through the weekend, maintaining small surf along north facing shores. A larger, long period northwest swell associated with Typhoon Malakas, will arrive Monday night, giving a noticeable boost to surf along north and west facing shores Tuesday through late next week.
