Hilo side: Wave heights for spots exposed to the swell are expected to be head high to overhead today. Spots without direct exposure will be smaller.

Our current long period south-southwest swell is expected to trend down through the rest of the week. Not much expected out of the SPAC anytime soon.
Our current large northwest swell will continue to slowly fade today 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.
