December: Dry, Clean and Fun-Sized Winter Waves
December is the quietest stretch of the year on paper, but it still offers plenty of surfable days. The average swell height is 4ft (1.2m) and the average period is 12.1s, with ideal offshore wind 59% of the time. The swell direction becomes more mixed: SSW holds the lead at 32.6%, S at 20.9%, but ENE/E/ESE/SE/SW add up to more than 35% of the total. This means smaller, more inconsistent energy and a greater reliance on wraps and sandbar tides at Chacahua. SSW contributes 22.5% in the 3-5ft (1-1.5m) class and S 12.8% in that same class, while ENE can occasionally offer 5-6.5ft (1.5-2m) pulses. The air is warm at 27.7°C, the water is 27.4°C, and rain is almost absent (0.18 mm/day). For anyone who likes clean, punchy, chest-to-head-high surf without the crowds, December is a solid option.
