December: Dark Months, Big Swells, High Reward
December closes out the year with a full-on winter statement. Average swell height reaches 7ft (2.1m), period is 11.7 seconds, and W, WSW and WNW swells combine for about 54% of all wave energy. The height distribution is rich with 5-8ft (1.5-2.5m) surf, and there is the first meaningful chance of XL, 8ft+ (2.5m+) days when the North Atlantic produces a powerful, widespread storm.
Despite the dark and cold, wind stats offer hope: ideal offshore winds are 25% of the time, and SSW/SW/WSW directions dominate the wind rose. Water temp has cooled to 11.1°C, air averages 8.7°C, and short days mean planning around tide and light. December can be punishingly stormy, but the clean offshore days between fronts are some of the most memorable of the year - the ocean is alive, the bay is working, and Tolcarne is at its raw, powerful best.
