Big Island Surf Forecast

Hilo: Wave heights are expected to be head high to well overhead today.

Kona: Wave heights are expected to be waist/chest high today or more for spots that pick up the wrap. The best breaks could get up to shoulder/head high on the sets.

South: Wave heights are expected to be knee/chest high today or more for spots that pick up the wrap.

Our current north-northwest swell is expected to slowly ease today through Saturday. Lots of variation for this swell since it’s coming from 330°… some spots are expected to reach advisory level depending on how exposed they are.

Thunderstorms are possible as early as Thursday night with the chance for thunderstorms extending through Saturday.

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.
