Big Island Surf Forecast
Hilo side: Wave heights for spots exposed to the large swell are expected to be shoulder/head high to overhead or more at the best breaks. Spots without direct exposure will be smaller.
Kona side: Wave heights are expected to be head high today. The best breaks could get overhead or more.
South: Wave heights are expected to be head high with the best spots getting bigger on the sets late in the day.
Our current large northwest swell is expected to build Thursday and peak in the afternoon. This swell is forecast to be a bit more westerly than the last one but the Kona side is again heavily shadowed by the other island and won’t get as big as the smaller islands. The swell will slowly fade Friday and into the weekend.
A small southwest swell is expected to show Thursday through Saturday. Another small bump could fill in the first week of March 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.
