Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A series small to moderate, medium to long period, northwest (320-330 degree) swells will pass through the local waters through early this weekend. These swells will produce elevated surf, though still well below High Surf Advisory, for north and west facing shores. A large, possibly extra large, northwest swell will likely reach the islands Sunday or Monday. This late season, long period, swell may produce warning level surf along exposed north and west- facing shores when it reaches the state early next week.

Expect elevated and choppy east shore surf for next several days as trade winds remain fresh to strong over and upstream of the state. South shore surf sets will hold at average waist high heights with the passage of a couple of very small, long period south swells.
