Conditions at Rodiles in December
December: Peak Reliability and Offshore Gems
December may be the best pure surf month on the calendar at Rodiles. The average swell is around 5-6ft (1.7m), the average period sits at a powerful 12.3 seconds, and the wind is ideal 61% of the time-the highest of any month. The wave rose is winter textbook: NW, NNW and WNW provide the bulk of energy, with consistent waves in the 3-8ft (1-2.5m) range and the potential for bigger, heavier sets as the storm track intensifies across the North Atlantic. A positive NAO keeps the lows marching toward Biscay, and when the wind settles out of the S/SSW/SW quadrant, Rodiles turns into a clean, rippable sandbar with real power. Water temperature is 14.2°C, air temperature 9.8°C, and rain runs 3.33mm/day-conditions are cold and dynamic, but the reward is the most dependable surf of the year.
