South: Breaks open to the trade swell could get up to head high or even overhead at the best exposures. Out of the south-southwest surf will be knee/waist high with the best breaks getting up to chest high on the sets.

Screen Shot 2015-12-15 at 7.25.21 PMA northwest swell is expected to continue filling in and peak Wednesday at or near advisory levels. The swell is forecast to diminish Wednesday night and Thursday.

A big surge in easterly winds has brought small craft advisory conditions over most coastal waters. Strong trades are expected for the second half of the week, in fact, winds may approach gale warning levels across the windier zones around the Big Island and Maui by late in the week.

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.
