Conditions at Les Cavaliers in December
December: Prime Time on the Côte d'Argent
December may be the best month of the year at Les Cavaliers. The data says it all: average swell 1.7m (6ft), average period 12.6s, and ideal winds 48% of the time - the highest of any month. The swell is solidly built from WNW (39.6%) and NW (32.4%), with an impressive concentration of 1.5-2m (5-6ft) waves (10.4% from WNW, 8.7% from NW) and plenty of 2-2.5m (6-8ft) energy. The wind pattern is the best of the year: offshore E/ESE/SE/SSE flow totals around 29%, while onshore W-WNW winds are relatively low (about 23%). This happens when a strong continental high fights the Atlantic lows, producing clean offshore mornings with ongoing NW groundswell. Water temp has fallen to 13.9°C and air temps average 7.7°C, so winter gear is mandatory. With the longest nights and strongest thermal gradients, December is the month to circle on your calendar for serious, high-quality surf on the west coast of France.
