December: Prime Time at La Setenta
December is prime time. The average wave height is 2.3ft (0.7m), the average period is 6.1s, and the wind is ideal 23% of the time. The seasonal pattern is fully locked in: N and NNW swells alone supply more than 25% of the monthly total, and when you add WNW and NW, the good window reaches about 34%. Solid 3-5ft (1-1.5m) waves appear regularly, with a meaningful share of 5-8ft (1.5-2.5m) sets out of the NNW. The North Atlantic storm track is at its most active, and NAO-driven swings can pull cold fronts farther south toward the Gulf of Mexico, which is often the recipe for a proper December swell at this spot. ENE swell remains present at 25%, keeping some cross-shore texture in the water, but the offshore S/SSW/SW/WSW wind days are frequent enough to make December the most reliable month of the year here. Water is still warm at 26.7°C, air temperatures average 23.4°C, and precipitation is low at 1.06 mm/day.
