Hilo side: Wave heights for spots exposed to the swell are expected to be shoulder high today with the best breaks getting slightly overhead. Spots without direct exposure to the swell will be smaller.
Kona side: Wave heights are expected to be knee/thigh high today. The best breaks could get a little bit bigger from time to time on the sets.
South: Wave heights are expected to be knee/thigh high today. The best breaks could get up to overhead or more on the sets for spots exposed to the swell.
Northwest swell down to leftovers. Another northwest pulse is possible for the weekend, building Saturday and easing Sunday. Another pulse is possible around May 3rd. The Big Island will largely be blocked.
Small south-southwest swell is expected to continue this week up to waist high. A fun swell is possible for May 1st.
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.
