Forecast for Big Island Windward and Southeast

Forecast for Big Island Leeward

Swell Summary

A small to moderate long period northwest swell (320 to 330 degrees) will build down the island chain today. This swell is expected to have continued reinforcements through Friday although all below High Surf Advisory levels. A medium period north (360 to 010 degrees) swell will continue to decline through Wednesday. This declining swell is still producing moderate surf along most north and exposed east facing shores.

A similarly sized northwest swell and a small north-northeast swell are possible this upcoming weekend. East shores will experience some wrapping north swell through Tuesday, followed by moderate, short period wind swell through Friday and potentially higher seas this weekend. South shores will remain seasonably small.
