December: Winter Kickoff and Clean Windows
December closes the year on a high note. Average swell height is 0.7m (2.3ft), period 8.4s, and ideal wind days rebound to 28%, just behind January's 30%. The swell rose shows E at 20.9%, ENE at 19.2%, NE at 16.0%, ESE at 13.5%, and NNE at 9.4%, leaving plenty of productive quarter energy. Wind directions are dominated by NNW (14.0%), NNE (9.0%), and NW (7.6%), but the offshore W-WSW sector also shows up strongly enough to create clean conditions after cold front passages. With water temp at 20.2°C (68°F) and air temps averaging 16.5°C (62°F), winter is setting in. This is the time to watch the NAO: when it turns negative, the Southeast U.S. can get more coastal low pressure and sustained NE swell, and Flagler Beach becomes a quality, hollow East Coast break. Early morning glass and dropping southwest winds after a front are your best bet.
