Conditions at Aviones in December
December: Winter Windswell With a Side of Chop
December is the most challenging month of the year for consistency at Aviones. Average swell height holds at 0.8m (2-3ft) and the average period climbs to 6.2s, with E swell dominating at 53.9 percent and ESE adding 30.1 percent. There is slightly more size in the E sector, but it is still short-period, locally generated windsea rather than true groundswell.
Ideal surf wind bottoms out at just 25 percent, the lowest of the year. ENE winds blow 25.1 percent of the time, E winds 34.7 percent, and cold front passages can easily flip conditions onshore out of the N/NNE. Water temperature cools to 27.4°C, air averages 25.5°C, and precipitation drops to 2.71 mm/day. The occasional perfect combination of a N/NW swell and a S/SW offshore breeze is the holiday jackpot, but patience is required in December.
