**Click directly on the images below to make them larger. Charts include: Big Island projected winds, tides, swell direction & period and expected wave heights.**
Hilo side: Wave heights are forecast from waist/head high today with onshore winds.
Kona side: Wave heights are expected to be knee/thigh high today.
South: Wave heights are expected to be waist high or less.
Multiple pulses of swell energy out of the northwest are expected for next week. Kona side will be heavily shadowed from these swells. The first pulse is due to fill in late Tuesday into Wednesday. A bigger swell is forecast to build Wednesday into Thursday with another pulse expected Friday and into the weekend.
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.
