Conditions at Las Gatas in December
December: Winter Groundswell, Westerly Winds and Holiday Surf
December closes the year with the smallest average swell of the year - 1.0m (3.3ft) - but with a very healthy 13.2s period. The swell distribution spreads out a bit more: SSW 42.8%, SW 43.1%, WSW 11.4% and W 1.7%. Most energy is in the 0.5-1m (1.6-3.3ft) and 1-1.5m (3.3-4.9ft) classes, making it a classic small-wave month for longboarders and funboard riders. The long period keeps the lines lined up and the reef working even when the height is modest.
Wind is a mixed bag: ideal offshore conditions occur only 24% of the time. NNW (18.3%), NW (16.0%), WNW (11.5%), W (10.6%) and WSW (7.9%) dominate, so afternoon conditions are often bumpy and cross-onshore. The best windows are early mornings before the continental breeze kicks up, or when a passing winter front leaves cooler, drier air and a brief offshore flow. Water temperature is 28.8°C, air temperature averages 24.8°C, and December is very dry with 0.19mm/day of precipitation. It may not be the biggest month, but a clean winter swell at Las Gatas is a deeply underrated thing.
