Hilo side: Wave heights for spots exposed to the trade swell are expected to be around chest/head high.

Kona side: Wave heights are expected to be knee/thigh high today or even flat.

South: Wave heights are expected to be waist high or less today. Strongest around South Point with trade swell filling in.

Screen Shot 2016-07-01 at 9.58.46 PMOld south energy is fading through the weekend. New swells will fill in over the weekend and into early next week. Not really notable though with wave heights not expected to get higher than waist high. Looking farther out, we may see another round of swell starting around July 7th.

Trade swell will bring surf to northeast exposures but onshore breeze will pick up quickly during the day to chop it up. Trade swell is expected to pick up this weekend.

Quiet in the North Pacific at this time. A possible swell may be generated in the Eastern Pacific later this weekend or early next week. We will keep an eye on it.

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.
