Our current north-northwest swell is fading Monday. New north-northwest swell will fill in for Tuesday. We have a couple more swells on track for the islands as well. Overlapping swells Friday and into Saturday are forecast.
Nothing significant is expected out of the SPAC with minimal leftovers expected this week.
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.
