Hilo side: Wave heights are forecast from shoulder high or more at the best exposures today.
Kona side: Wave heights are expected to be knee/waist high from wrap out of the northwest but dropping. Otherwise, it should be pretty flat.
South: Wave heights are expected to be knee/waist high or more from wrap out of the northwest depending on the exposure but dropping through the day. Otherwise, it should be pretty flat out of the south.
Our current northwest swell is fading through the day today with some sneak sets still filtering in through the morning. The surf should trend down through the upcoming weekend along north and west facing shores.
A modest trade swell will continue for north and east exposures.
A small to moderate south swell associated with a recent batch of gales over the Tasman Sea is expected to hold through Friday night before easing.
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.
