Conditions at La Boya in December
December: The Crown Jewel Month
December rounds out the year as La Boya's most consistent mix of size, period and direction. Average swell reaches 3.5ft (1.1m) with a 6.1s period, and the swell rose shows the most balanced distribution of the year: ESE 33.7%, E 33.5%, ENE 17.8%, plus NE and NNE combined near 10%. Ideal wind is at 14%, supported by strong cold fronts dropping out of North America. Those fronts can flip the trades into a light offshore W/WNW breeze for consecutive days, turning the usual trade mush into clean, lined-up 3-5ft (1-1.5m) surf. Water temp is 27.4°C (81°F), air 25.7°C, and rain drops to 1.32 mm/day. This is the gateway to the prime winter season.
