Hilo side: Wave heights are expected head high today with the best breaks getting up to overhead from time to time on the sets.
Kona side: Wave heights knee/waist/chest high are expected today. The best breaks could get up to shoulder high on the sets.
South: Breaks open to the south-southwest swell could get up to waist/chest high. The best spots open to the trade swell could reach shoulder/head high on the sets. Trade swell exposed areas could get up to head high or overhead.
A new south-southwest continues Thursday and holds through Friday. A slightly bigger swell is expected for the weekend with a reinforcement on tap late in the weekend into early next week.
A short-lived northwest swell is for the weekend, building Saturday evening and holding through Sunday morning before beginning to fade.
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.
