December: The Dry-Season Reset
December settles into the full dry-season pattern. The northeast trade wind machine is back in force, with NE at 50.7% and ENE at 29.2% of wind observations. Ideal wind conditions reach 75%, producing some of the cleanest, glassiest morning surf of the year. Air temperatures are warm around 27.1°C, precipitation drops to 0.70mm/day, and water temperature holds at 27.8°C. If you are looking for clean, small, shaped waves, December delivers.
The swell, however, is the weakest link. Average height is 1.3m (4ft) and the period drops to 11.7s, the lowest of the year. While SSW at 31.1% and SW at 18.7% still contribute, the wave rose broadens significantly toward E/SE and NW/NNW directions, meaning much of the approaching energy is not optimally aligned with the WSW-facing beach. The best surf comes from intermittent SSW/SW pulses riding underneath the persistent offshore trades. It is not the season for heavy barrels, but it is a good time for clean, rippable walls and high wave counts on a blissful tropical beach.
