Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A moderate size, medium period north (010 degree) swell moving through the islands is forecast to peak through the day. North- facing harbors, particularly Kahului and Hilo Harbors, may experience minor surges from this incoming north swell through the day. A similar size moderate, medium to long period northwest (310 degree) swell will be arriving in Kauai's nearshore waters early this morning and reach Maui during the early afternoon hours. This swell will likely increase north and west-facing shore surf heights to near High Surf Advisory levels at its peak tonight into early Monday. Choppy, moderate trade wind swell may slightly decline today before rebuilding early this week and maintaining a rough chop along east-facing shores for several days. No significant south swell expected this week will result in very small south-facing shore surf.
