HIGH SURF ADVISORY FOR NORTH AND EAST FACING SHORES

Swell Summary

The combination of a medium period north to north-northeast (010 to 020 deg) swell and a short period north-northeast to northeast (020 to 040 deg) swell will produce large and rough surf above High Surf Advisory levels along north and east shores through Tuesday. The north to north-northeast swell will decline late Tuesday, and even as a long period northwest swell builds in on Wednesday, north shore surf is expected to be below the advisory threshold. The northwest swell will lower through Friday, followed by another small to moderate northwest swell Sunday.

As the current north swell fades late Tuesday, a large short period northeast (040 to 050 deg) swell will persist due to a belt of near gale to gale force northeast winds several hundred miles northeast of Hawaii. This will keep rough east shore surf well above the advisory level, with surf possibly reaching as high as the High Surf Warning mark of 15 ft on Wednesday. Expect the northeast swell energy to lower as local trade winds begin to decline on Thursday, with east shore surf steadily dropping on Friday and the weekend.

A small south swell is maintaining south shore surf near summertime background levels. A slightly larger pulse may arrive on Tuesday, peak on Wednesday and early Thursday, and then fade by Friday.
