December: Winter Pattern Locks In
December turns the corner into the best stretch of the year. Average swell height is 0.9m with an average period of 8.6s. Swell energy is split nicely between ENE (24.2%), E (23.4%), NE (15.3%), NNE (9.4%) and even NNW (6.2%), giving a variety of exposed sandbars plenty of work. The key difference is wind: ideal wind jumps back to 22% of the time, with NNW (12.9%), NW (8.0%) and WNW (6.0%) combining for excellent cross-offshore/offshore flow. These are the conditions that turn a standard 2-4ft (0.6-1.2m) day into a clean, rippable session. Water temp drops to 22.3C, air temp is 19.1C and precipitation is just 2.09 mm/day, making December a reliable month to score before the heart of winter sets in.
