Hilo side: Wave heights are forecast from chest/head high today. The best breaks could get up to overhead.
Kona side: Wave heights are expected to be waist high or less. Most spots will be flat.
South: Wave heights are expected to be chest/head high for spots catching the trade swell. Otherwise, it should be pretty flat out of the south.
Some north-northwest energy is due in over the weekend. Up to shoulder high waves are expected for the Hilo side during that time.
East-northeast trade swell will bring chest/head high waves to exposed spots with sets getting up to overhead.
Nothing significant is expected out of the SPAC with minimal leftovers expected this week.
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.
