Big Island Surf Forecast

Hilo side: Wave heights for spots exposed to the trade swell are expected to be waist/shoulder high today.

Kona side: Wave heights are expected to be knee/thigh high today, some spots could get up to waist high on the sets at the best exposures.

South: Wave heights are expected to be knee/thigh high today, some spots could get up to waist high on the sets at the best exposures. Spots catching trade swell could get up to waist/shoulder high.

Our current south-southwest swell is slowly fading through the weekend.

Trade swell will hold for the next few days with onshore conditions for windward sides.

Pre-season north-northwest swell is expected for Friday and Saturday. The Big Island will be heavily shadowed from this swell.

Models are showing activity in the West Pacific so there is potential for swell energy out of that region in the future.

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.
