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.
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 Hemi 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.
