Conditions at Gaztetape in December
December: Winter Peak Arrives
December is the crown jewel of the Gaztetape surf season. Average swell height reaches 2.0m (6-7ft) with a powerful 12.4s period, and the beaches get hit by consistent NW (28%) and WNW (24%) groundswell, with W and NNW adding more size. The wave heights are solid: a large chunk of observations fall in the 1.5-2.5m (5-8ft) range, with occasional 2.5m+ bombs. Ideal wind frequency peaks at 45% - the highest of any month - thanks to a strong dominance of S (21%) and SSW (13%) winds. December is the month when everything lines up: big, long-period swells, offshore winds, and the cold, dense air that gives the surf extra punch. It doesn't get much better than this.
Air temps average 10.7°C, water 14.2°C, and precipitation is 3.82 mm/day. Winter wetsuit territory, but the waves make it all worthwhile.
