Conditions at Tiruchendur in December
December: Short-Period NE Swell And Strong Winds
December is back to the winter monsoon pattern - lots of ENE (37%) and NE (24%) swell, but at a short-window 8.2s average period. The average height is 1.0m (3ft), with many waves in the 1-1.5m range, but the lack of period makes them fat, lumpy and difficult to ride. Wind is the bigger problem: NNE (35%) and NE (37%) combine for nearly three-quarters of the observations, and the ideal offshore wind share drops to just 9 percent. This creates a persistent onshore/cross-shore chop that wrecks the shape of the easterly swell. Clean days are rare, but when a high-pressure system lingers over the interior and the morning land breeze aligns with an ENE swell, the beach can still turn on for a few fun 3-4ft (0.9-1.2m) waves. Air temps cool to 25.9°C, water remains warm at 27.7°C, and rainfall is only 2.35mm/day, making December a dry but frustratingly fickle month.
