Hilo side: Waist/shoulder high waves expected today for east exposed breaks.
Kona side: Wave heights of ankle/knee high are expected for the best southerly exposures.

Our current south-southwest swell is expected to slowly fade to leftovers by Wednesday. A fun swell is expected to reach us out of the South Pacific Thursday/Friday peaking over the weekend with a reinforcement right on its heels.
Trade swell it expected to pick up midweek through the end of the work week in the waist/chest high range.
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.
