Big Island Surf Forecast

Hilo side: Surf heights are expected to be waist/shoulder high today.

Kona side: Surf heights are expected to be knee/waist high today. The best exposures could get a bit bigger on the sets. Exposures not open to the swell will be flat.

South: Surf heights are expected to be knee/waist high today. The best exposures could get a bit bigger on the sets.

New small southwest is forecast to peak Wednesday and fade thereafter. A south-southeast will blend in to that. Not expected to get very much past waist high.

Fun north-northwest pulse is forecast to gradually ease up through Wednesday. A small north-northwest reinforcement is forecast to fill in Wednesday night but it should be short-lived and fade pretty fast on Thursday.

Trade swell is forecast to continue to build Wednesday and could be at advisory levels by Thursday.

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.
