Hilo side: Wave heights are expected head high to overhead with the best breaks getting up to well overhead today.

A big surge in easterly winds has brought small craft advisory and gale warning conditions over the coastal waters. Trade swell is expected to gradually ease over the next couple of days as winds weaken some. The rough seas will maintain high surf along east facing shores of the islands. The high surf warning for east facing shores has been cancelled but a high surf advisory is posted through midweek.
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.
