Hilo side: Messy waist to shoulder high trade swell waves are expected today. The spots best exposed to the swell could reach overhead on the sets.
Kona side: Wave heights of ankle to waist high are expected.
South: Wave heights of knee to shoulder high are expected.
A solid northwest swell will continue to build for the northeast coast early Thursday, peak late Thursday and slowly fade out Friday into the weekend. Best spots are expected to be overhead at the peak.
A reinforcing northwest is expected to move in Sunday.
Small south-southwest reinforcement swell tops out Thursday. Otherwise, nothing much on the horizon out of the South Pacific.
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.
