Screen Shot 2016-08-17 at 11.38.57 PMOur current south-southwest swell is holding Thursday before slowly fading through the weekend.

Trade swell will hold for the next few days with onshore conditions for windward sides.

Pre-season north-northwest swell is expected for Friday and Saturday. The Big Island will be heavily shadowed from this swell.

Models are showing activity in the West Pacific so there is potential for swell energy out of that region in the future.

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.
