Screen Shot 2016-03-29 at 9.21.29 PMOur current long period south-southwest swell is expected to fill in further and peak on Wednesday up to shoulder high at the best spots. Not much expected out of the SPAC anytime soon.

Our current large northwest swell will continue to build Wednesday and peak in the afternoon. The Big Island will largely be blocked from this swell but some size will still filter in up to about overhead at the best exposures. This has prompted a High Surf Advisory to be issued. This swell is expected to slowly trend down Thursday into Friday.

Models are showing another northwest swell around April 6th. Will keep an eye on the progress.

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.
