Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

Small surf will persist along north and west facing shores through Wednesday. An extra large northwest (320 degrees) swell will arrive late Wednesday night and rapidly build down the island chain on Thursday, pushing surf well above High Surf Warning levels for most north and west shores through Friday. Coastal impacts are possible, and moderate to fresh north winds developing with the swell will result in rough conditions. A pulse of large, medium period north swell will follow on Saturday and Sunday, keeping surf above the High Surf Advisory level for exposed north facing shores.

Surf along east facing shores will trend up sharply during the weekend due to a combination of rough, short period trade wind swell and the large north swell. Typical midwinter very small conditions will prevail for south shores.
