Hilo side: Mix of trade wind swell still holding on and fading north-northwest. Waist to head high surf expected for the best breaks.

Kona side: Surf is expected ankle to knee high. The best breaks may see chest high waves on the sets.

South: Mix of trade swell and fading south-southwest will bring wave heights up to chest high, maybe bigger at the best exposed shores and breaks.

Wave heights are on a downward trend for all shores. Trade swell will be in the mix for the Hamakua, Puna and Ka’u coastlines and to a larger extent starting Thursday as winds pick up.

Screen Shot 2014-12-16 at 8.42.38 PMA small northwest swell is expected to peak late Wednesday and linger through Thursday. This swell is heavily shadowed. A new west-northwest is expected to fill in Thursday evening and peak on Friday morning head high to overhead on the sets at the best breaks.

Another west-northwest swell is expected late Sunday depending on how the storm develops.

An out of season south swell that brought a fun little boost the last couple of days will linger but slowly fade through the week. Nothing significant is expected out of the SPAC.

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.
