Hilo side: Wave heights are forecast from knee/shoulder high today.
Kona side: Wave heights are expected to be flat in the morning and rise to knee/waist high by sunset.

Back to back pulses out of the North Pacific are lining up this weekend and early next week. The first storm developed in the northwest Pacific and is sending our first good size northerly swell for the winter season. The Big Island will be mostly blocked unfortunately. Northwest swell builds late Saturday and peaks Sunday before fading Monday and Tuesday. Another swell is expected to build late Tuesday as well.
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.
