Hilo side: Wave heights are expected chest/head high today from the trade swell. The northwest swell is expected to bring wave heights up to overhead or even double overhead at standouts on the sets.
Kona side: Wave heights knee/waist 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 northwest shifting north-northwest swell is expected to continue. For the Kona side size is decreasing as the swell shifts. For the Hilo side size will build. 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.
