Forecast for Big Island Windward and Southeast

HIGH SURF ADVISORY FOR EAST FACING SHORES

Forecast for Big Island Leeward

Swell Summary

Though rough conditions persist, surf along exposed north and west facing shores have decreased below High Surf Advisory (HSA) threshold this morning. This advisory has been dropped for those shores with this morning's forecast package. However, thanks to continued elevated easterly wind waves and a mix of a medium- period northeast (020-040 deg) and a long period northwest (310 deg) swells, surf heights along east facing shores will continue to reach HSA threshold. The HSA has been extended only for east facing shores through this afternoon. The northeast and northwest swells will slowly decline over the next couple of days as wind waves also ease.

Models show the next significant northwest swell will move into the region Friday into the weekend.
