Hilo side: Wave heights are expected chest/head high today from the trade swell. The new northwest is expected to bring wave heights up to overhead by the afternoon with the best breaks being even bigger.
Kona side: Wave heights waist/chest high for spots catching the northwest wrap.
South: Breaks open to the trade swell could get up to waist/head high. Otherwise, south-southwest is around knee high.
Our current west-northwest shifting northwest swell is expected to continue to build and peak on Wednesday. Should show best for the Kona side on Wednesday and the northeast coast Wednesday afternoon and Thursday. 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.
