Hilo side: Wave heights are expected head to well overhead today early on with a downward trend expected.
Kona side: Wave heights knee/waist high are expected today. The best breaks could get a bit bigger on the sets. Some north-northwest will filter in for spots open to the swell.
South: Wave heights are expected knee/waist high today. Best breaks open to the swell could get up to belly/tummy high on the sets.
Another more ‘westerly’ swell (295° to 315°) is expected on the heels of the current swell energy. This swell is forecast to quickly build late Thursday and mix in with our current swell for head high to well overhead waves. This swell should peak late Friday before slowly fading.
Our current south-southwest is down to leftovers today. A new south-southwest fills in Thursday/Friday to keep wave heights around knee/waist/chest high.
Next week another pulse of south-southwest is expected. Will keep an eye on it.
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.
