Conditions at Carnon in December
December: The Crown Jewel of the Winter
December holds Carnon's highest statistical potential. The average wave height is 2ft (0.6m), the average period is 4.7s, and the ideal-wind window reaches its annual peak of 9%. Swell comes consistently from S (12.8%), SSE (8.5%) and SE (8.4%), and the S direction shows a healthy spread of 1-1.5m (3-5ft) waves (2.2%) alongside a few bigger pulses. The real game-changer is the wind: combined offshore flow from N, NNE, NW and NNW totals 50.9%, with NNW leading at 18.4% and NW at 15.3%. This is the Mistral season firing exactly when the Mediterranean low-pressure engine is most active. Yes, the period is still short, but offshore-flow + SE/S swell is the sweet spot for this south-southeast-facing stretch of sand. Sea temp is 12.3°C, air temp 8.0°C, and the reliable winter surf makes the cold worthwhile.
