December: Winter Groundswell Ramps Up
December brings the winter swell machine into full swing. Average swell height increases to 3.3ft (1.0m) with a long 13.3s period, and the direction profile flips back to north-western dominance: WNW at 27.7%, NW at 16.7% and W at 12.7% lead the pack, with WSW at 7.3% and SW at 5.6% providing additional west-southwest energy. This is prime time for larger, longer-period groundswell; the 3-5ft (1-1.5m) range is the most common, but some WNW/NW pulses push into the 5-8ft (1.5-2.5m) zone. Offshore wind is available 28% of the time, so there are frequent opportunities for clean conditions, especially before the afternoon onshore sea breeze. Water temp cools to 25.2°C, air temp averages 24.9°C, and rainfall remains high at 2.54mm/day as the islands enter their wet season. December delivers some of the best all-around surf of the year at Pine Trees.
