Kona side: Wave heights waist/chest high and up to occasionally shoulder high.
South: Most breaks are waist/chest high and up to occasionally shoulder high. Breaks open to the trade swell could still get up to head high or even overhead.
Our current swell has shifted northwest and is expected to shift farther out of the north-northwest on Friday as the swell also starts a downward trend. A small northwest is expected Sunday into Monday.
Trade swell holds through the week with head high to overhead surf.
A new south-southwest is expected to peak Friday and Saturday around waist/chest high and fade Sunday. Nothing of note otherwise.
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.
