Forecast for Big Island Leeward

Swell Summary

Trade winds will produce moderate, choppy surf along east facing shores through today, then slowly trend lower tonight through mid-week due to weakening trades near and upstream of the islands. Moderate and choppy surf will return later in the week as trades strengthen.

The current small south swell and associated south shore surf will continue to subside through the day to summer average heights. Through mid-week, short- to medium-period southeast trade wind swell energy from the southern hemisphere will keep small surf along exposed shorelines.

Surf will remain nearly flat along most west and north facing shores through mid-week. Small west-northwest swells, from tropical cyclone activity in the NW Pacific, may arrive along some exposed west and north facing shores starting Thursday or Friday. However, confidence about the timing and the size of these swells remains low at this time.
