HIGH SURF ADVISORY FOR EAST FACING SHORES

Swell Summary

Nearshore buoys and surf observations continue to show advisory level surf along east facing shores with very little change among wave heights on the buoys during the past few days. Surf should begin to gradually ease tonight into Friday then steadily decrease over the weekend.

Surf along north and west facing shores will remain well below seasonal levels through the weekend, and surf along south facing shores will remain small. Some trade wind swell will continue to wrap into select north and south facing exposures.

Forerunners from a large, long-period north to north-northeast swell are forecast to arrive Sunday night, then rapidly build to near warning levels along north facing shores Monday through Tuesday. Also due to the northerly direction, elevated surf heights are expected along west Maui and west Big Island near Kua Bay. Surf heights are expected to reach advisory threshold for west Big Island on Monday and could reach advisory threshold for west Maui as well. Lastly, due to the large swell and northerly direction (010-030 degrees), heavy surges are expected along north facing harbors such as Kahului and Hilo harbors.
