December: Trade Swell and the Summer Sea-Breeze Cycle
December settles into the full summer pattern. Average swell height is 4-5ft (1.4m), average period is 8.1s, and ideal wind drops to 35%. The swell direction statistics are dominated by E (17.6%), ESE (16.6%), SE (15.4%), ENE (14.8%), NE (14.0%) and SSE (12.1%) - a classic easterly trade and windswell mix. There is enough energy in the water for fun, rippable waves, but the short period means less power and more bump. Winds are onshore/cross-onshore much of the time: SSE (12.1%), SE (9.6%), NE (9.7%) and NNE (9.5%) lead the rose, with offshore W/WNW/NW/NNW at only about 18%. The 35% ideal-wind figure hides a daily pattern: clean, often glassy mornings, followed by a predictable afternoon seabreeze. With air temperatures at 23.8°C, water at 23.2°C and precipitation around 4.11 mm/day, December is warm, humid and best handled by surfers willing to dawn patrol.
