Conditions at Xivares in December
December: Prime Winter Window
December is the ultimate month at Xivares. Average swell is a powerful 5.2ft (1.6m), with an average period of 12.4s, meaning the Atlantic is throwing heavy, long-period lines into the beach. The directional spread is textbook: NW at 39.2%, WNW at 17.6%, NNW at 18.1%, and NNE at 6.2%, with a solid chunk of 1.5-2.5m groundswell (NW 11.9% in 1.5-2m and 8.3% in 2-2.5m). Most importantly, ideal wind hits 61%, the highest of the year - S (13.7%), SSW (8.6%), SW (8.6%), and SSE (7.2%) combine for consistent, glassy offshore conditions between frontal passages. The ocean temp is 13.9°C and the air is cold (9.8°C), but when the sky clears after a storm, you get the full north-coast experience: powerful NW swell, offshore winds, and cold-air lumps that look like they belong in a surf movie. This is the peak of the peak.
