Conditions at Pacifico in December
December: Big Winter Swell, Rough Conditions
December ushers in the true arrival of the Northeast Monsoon, and Pacifico's good surf season comes to an abrupt halt. The average swell height jumps to 1.6m with a long 10.0s period, delivering plenty of raw energy. But the direction is all wrong: NE (60.1%) and ENE (24.8%) dominate the swell rose, while western-quadrant swell is virtually absent. The wind data seals the deal-ENE (28.4%), NE (19.4%), E (16.5%), and ESE (8.8%) make ideal wind time a pitiful 4%. This means strong, onshore-blown, wind-chopped conditions for the majority of the month. The occasional cold-front-driven NW wind or a rogue typhoon can briefly improve the surf, but those are rare. Precipitation climbs to 14.84 mm/day, air temps remain tropical at 27.7°C, and water temperature is 28.4°C. December is for the storm chasers who can handle big, raw, messy Pacific energy; for the average surfer, it's time to look elsewhere or wait for the next summer's magic.
