Kona side: Wave heights knee/thigh high are expected today. Spots not catching swell will be flat.
South: Wave heights knee/waist high are expected for the breaks open to the south-southwest. Trade swell mix is expected up to waist/shoulder high.
Our current south-southwest swell is expected to linger. Meanwhile, models continue to show a couple of tropical systems flaring up to the southwest which could generate swell for the islands. Will keep an eye on it.

East-northeast swell mix is expected through Friday. Solid shot of north-northeast expected to build overnight Friday and peak late Saturday into early Sunday.
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.
