Big Island Surf Forecast
Hilo side: Wave heights for spots exposed to the swell are expected to be shoulder/head high today. Spots without direct exposure to the swell will be smaller.
Kona side: Wave heights are expected to be knee/thigh high today.
South: Wave heights are expected to be waist high or less today out of the southwest. Spots with exposure from wind waves could be bigger than that, up to slightly overhead at the best breaks.
A new west-northwest is expected to build late Wednesday and peak Thursday at about waist high before fading Thursday and Friday. Otherwise nothing of note is expected.
A small south-southwest swell will show through Thursday with the best breaks up to chest high on Tuesday. Another swell is expected Friday and into the weekend with waist/chest high surf expected.
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.
