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

Today we have a mix of south-southwest swells, one is fading and one is building. Tuesday swell size will hold before trending down. Nothing much expected out of the SPAC anytime soon.
Old north swell is expected to fade today with the energy dropping further through the afternoon and Tuesday. A small west-southwest swell is expected Wednesday and Thursday with a small north-northwest possible for Friday into the weekend.
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.
