Conditions at Roads End in December
December: Maximum Winter, Maximum Reward
December posts the biggest average swell of the year at 2.8m (9.2ft) and a powerful 12.8s period. The direction distribution is again optimal, with W (17.7%), WNW (16.8%) and WSW (7.0%) leading the way, plus NW (2.3%) and SSW/SW contributions as lows track closer to the coastline. This is serious, heavy, long-period surf - often in the charging and XL category. Ideal wind holds at 33%, and the offshore E/ESE/SE pattern is common enough that clean, big-wave sessions are not rare. That said, when the wind switches west or northwest, conditions become dangerous and unruly. Expect the coldest, wettest weather of the year: air 5.0°C, winter water 10.2°C and 9.00 mm/day of rain. December at Roads End is not for the faint of heart, but for the prepared surfer it delivers the best waves of the season.
