New NW Builds Today

Hilo side: Knee to belly high trade wind waves are expected today. New northwest swell builds up to chest high or more by sunset.
Kona side: Wave heights of ankle/waist high are expected.
South: Wave heights knee/waist high today with sets reaching about belly high.
Our current south-southwest swell is expected to fade through the early part of this week. This week is looking pretty quite out of the southern hemisphere. Next week we could see some activity around May 5th or 6th pending development of storms.
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.
