Hilo side: Wave heights are expected chest/head high today with the best breaks getting overhead from time to time on the sets early in the day.
Kona side: Wave heights knee/thigh high today.
South: Most breaks are knee high or less. Breaks open to the trade swell could still get up to waist/shoulder high.
Our current northwest swell is expected to hold through the morning before beginning a steady fading trend. A reinforcing northwest swell is expected to arrive late Tuesday, and then peak on Wednesday. This swell could once again bring advisory level surf to exposed shores. An even larger northwest swell is possible for the next weekend, which could bring surf to warning levels.
Our current south-southwest is mainly leftovers today.
Trade swell continues but it’s bumpy and sloppy for most spots.
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.
