December: Winter Groundswell and Post-Frontal Grooming
December brings classic winter surf. Average height holds at 4ft (1.2m), period is 8.0s, and ideal wind improves to 22%. The swell distribution is nicely spread across NE (21%), ENE (19%), NNE (14%), E (13%), with NNW (7%) and N (5%) representing strong offshore lows. Many of these waves arrive in the 1-1.5m sweet spot, with consistent 1.5-2.5m sets as storms roll through. As cold fronts become more frequent, the winds switch around much more; E and ENE still dominate onshore, but NW and W winds become a bigger feature, NW 7%, WNW 5%, W 3%, creating those coveted offshore winds that groom the NE-E swell into clean faces. Air temps cool to 21.6°C, water is 25.1°C, and precipitation drops to 2.11mm/day. Solid, punchy winter surf is the rule.
