**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 knee/waist high today.
Kona side: Wave heights are expected to be waist high or less. Most spots will be flat.
South: Wave heights are expected to be waist high or less. Otherwise, it should be pretty flat out of the south.
Our current northwest swell is forecast to continue Friday but the Big Island is largely shut out from this energy, at least for the Kona side. Some north-northwest energy is due in shortly thereafter over the weekend. Up to shoulder high waves are expected for the Hilo side during that time.
A modest trade swell will continue for north and east exposures.
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.
