Conditions at La Sud in December
December: Winter's Reliable Hammer
December closes the year in classic winter form. Average swell height is 5-6ft (1.7m), period reaches 12.6 seconds, and ideal offshore wind tops the annual list at 39%. The swell direction remains locked on WNW (39.6%) and NW (32.4%), supported by a secondary push of W and WSW swell that adds extra variety. The 1.5-2.5m range is well represented, and the wave period is long enough to make the most of every push of energy. Water temperature drops to 13.4°C, air averages 7.7°C, and precipitation returns to a significant 3.6mm/day. December is prime time: maximize the windows with east winds, because the ocean is consistently firing.
