A west-northwest swell is holding through the day Monday at warning levels. This swell is expected to show best for the Kona side. Surf fades through Wednesday and becomes messy as a front moves through. The Hamakua coast will not see much wrap but instead experiences more trade wind swell out of the southeast. Another solid shot of energy out of the northwest is forecasted to combine with northeast wind swell on Christmas Day.
An out of season boost will continue to fade with waist high waves or less at the best exposures. Otherwise, nothing significant is expected out of the SPAC.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
