Conditions at Les Culs Nuls in December
December: Winter Premium Quality
December is the equal of February for overall surf quality at Les Culs Nuls. Average swell height reaches 5-6ft (1.7m), the period stretches to a powerful 12.6s, and favorable winds blow 38% of the time, tied for the best of the year. WNW (40%) and NW (32%) remain the dominant swell producers, and the distribution of wave heights skews solidly into the 1-2.5m (3.3-8.2ft) range. E and ESE winds are common in the wind rose, meaning clean offshore conditions frequently align with new groundswell. Air temperatures are cold at 7.7°C and water drops to 13.4°C, so proper winter rubber is essential. The nights are long and the water is cold, but December offers some of the most consistent, high-quality surf of the entire year. Watch for the high-pressure ridges that turn the wind offshore and transform the North Atlantic energy into perfect peaks.
