Hilo side: Wave heights are forecast knee/shoulder high today for the best breaks.
Kona side: Wave heights are expected to be ankle/knee high today. By sunset, new northwest could get up to waist high.
South: Wave heights are expected to be ankle/knee high today. Wrap from the northwest swell will make exposures open to that direction a bit bigger, especially late in the day.
Our current mix of northeast and northwest swell is lingering into Monday. Very small reinforcement building into Monday but it will be greatly shadowed for the Kona side of the Big Island. A stronger pulse is on the radar for the 13th and the 16th.
Nothing significant is expected out of the SPAC in the near future.
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.
