HIGH SURF ADVISORY FOR WEST FACING SHORES

Swell Summary

A fresh pulse of medium-period WNW swell will support advisory level surf along exposed N and W facing shores today. This swell will gradually diminish Friday and Saturday. Another WNW swell will arrive Sunday and Monday, likely leading to High Surf Advisory level surf along many N and W facing shores, including leeward Big Island. This swell may continue to build on Tuesday, pushing surf heights to High Surf Warning levels along exposed shores. This swell is expected to diminish next Wednesday and Thursday. Short-period choppy wind waves along S and W facing shores will ease as winds diminish the next couple of days, but will likely redevelop over the weekend as SW winds increase again. East facing shores have minimal surf and a distinct lack of wind waves.
