Hilo side: Wave heights for spots exposed to the swell are expected to be double overhead or more today. Spots without direct exposure will be smaller and spots with the best exposure could get up to triple overhead.
Kona side: Wave heights are expected to be knee/waist high today. Spots with less exposure will be much smaller.
South: Wave heights are expected to be knee/shoulder high today and strongest around South Point.
Our current south-southwest bump continues to fade as a new small south-southwest swell fills in into the weekend. Sunday this swell will begin a fading trend.
A solid north swell is expected to continue through the weekend. Another good dose of northwest swell is expected to move in late Saturday and peak Sunday before fading out early next 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.
