Hilo side: Wave heights for spots exposed to the swell are expected to be knee/waist high today. Spots without direct exposure to the swell will be smaller.
Kona side: Wave heights are expected to be knee/thigh high in the morning, building to waist/chest high today by the afternoon.
South: Wave heights are expected to knee/waist high in the morning with chest high sets by end of day.
A fun southwest swell is expected to build Thursday and peak Friday and Saturday around shoulder high at the best breaks before fading Sunday. Some energy is expected to filter in from May 30th through June 2nd.
A storm is possible in the northwest Pacific so this could mean some swell energy filling in around the 30th. The Big Island’s Kona side will likely be heavily shadowed. Trade swell will continue to affect northeastern exposures but onshore winds mean messy conditions.
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.
