Hilo side: Wave heights for spots exposed to the wrap are expected to be waist / head high at the best breaks. Occasionally we could see overhead waves on the sets.
Kona side: Wave heights are expected to be chest / head high today. On the sets the best spots with west-northwestern exposure could see waves in the overhead range.
South: Out of the southwest knee/thigh high today. Some spots around South Point may get wrap out of the west-northwest up to chest/head high or maybe more on the sets.
The current warning level west-northwest swell will continue to affect north and west facing shorelines, although a fading trend will be in effect Tuesday. Another warning level northwest swell is expected to arrive Tuesday night, peak late Wednesday and Wednesday night, then lower slowly Thursday and Friday.
There will also be a series of small, mainly background south swells through the week.
Easterly trade wind swells will remain rather low for the next several days.
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.
