Hilo side: Wave heights from waist to head high are expected, the best breaks could be bigger on the sets.
Kona side: Wave heights from ankle to belly high are expected.
South: Wave heights of knee to waist high are expected. Standout spots could get up to chest high on the sets.
A mix of short to mid period north-northwest swell energy and northeast trade swell is expected to linger the next few days.
A south-southeast and south-southwest mix of swells is expected to hold through Thursday. South shores are expected to go quiet from Friday through the first part of next week.
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.
