Big Island Surf Forecast

A new northwest swell is forecast to fill in Monday and peak Tuesday / Wednesday before easing the second half of the work week. The middle of the month looks to be quite active. Storm developing in the northwest Pacific could bring a good size swell for next week. Stay tuned.
Nothing significant expected out of the South Pacific any time soon.
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.
