December: Big Winter Swell, Tricky Winds
December delivers the goods in size but struggles with surface conditions. Average swell reaches 1.6m (5.2ft) at a solid 10.0s period, and the direction is extremely consistent: NE (60.1%), ENE (24.8%), and NNE (7.9%) combine for about 93% of observations, with most waves in the 1.5-2m (4.9-6.6ft) and 1-1.5m (3.3-4.9ft) classes. That means pumps of proper NE groundswell hitting the beach. However, the northeast monsoon is in full force: NE (18.5%), ENE (24.9%), E (15.5%), and NNE (8.4%) winds, mostly in the 10-30km/h range, keep the face lumpy. Ideal wind is only 4%. Air temperature sits at 27.7°C, water at 28.4°C, and precipitation is high at 14.8mm/day. For bigger, cleaner Stimpy's waves, you need a strong southwesterly push or a rare dawn patrol between monsoon squalls.
