December: Small Swell, Long Period, Winter Texture
December closes the year in the low surf season. Average wave height falls to 3.3ft (1.0m), although the period remains long at 13.2 seconds. The swell is split fairly evenly between SW at 43% and SSW at 43%, with WSW adding another 11% and only a sliver of W energy. Wave heights are dominated by 2-5ft (0.5-1.5m) surf, with just a handful of larger sets. Wind quality is limited, with ideal conditions only 23% of the time; NNW and NW winds account for a huge share of the wind rose and tend to add cross-onshore texture. Air temperature averages 24.8°C, rainfall is scarce at 0.19 mm/day, and water temperature is 28.8°C. For small-wave surfers, December can still offer playful long-period waves on the right day, but do not expect the size and power of summer.
