Big Island Surf Forecast

Hilo: Wave heights are expected to be overhead to double overhead today.

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

South: Wave heights are expected to be chest/head high today or more for spots that pick up the wrap. Spots that don’t pick up the wrap will be ankle/waist high today.

Our current north-northwest swell is expected to peak into Wednesday morning and bring another round of advisory level surf for the Big Island. 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.

A cold front is forecast to move down the island chain today.

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.
