Hilo side: Wave heights are expected overhead to well overhead today. The best breaks could get up to double overhead on the sets.

Kona side: Wave heights are expected to be below waist high today.

South: Breaks open to the trade swell could get up to overhead at the best exposures. Out of the south-southwest surf will be below waist high.

Screen Shot 2015-12-18 at 5.28.33 PMOur current north-northwest swell will continue to slowly ease today. A new north swell is expected to build Sunday into the waist/shoulder high range or so.

A big surge in easterly winds has brought small craft advisory and gale warning conditions over the coastal waters. Trade swell will continue as long as the winds are up.

Nothing of note expected out of the Southern Hemisphere for the final weeks of 2015.

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.
