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. The rough seas will maintain high surf along east facing shores of the islands. The high surf warning for east facing shores goes through Monday night, and may need to be extended into Tuesday. Other surf sources this week include small NW swells Tuesday and Thursday.
A northwest swell is expected to slowly build Monday, peak Tuesday and ease Wednesday.
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.
