December: Peak Size, Tricky Winds
December is the peak of the winter size window, with the average wave height at 6ft (1.8m) and the period at 6.8s. The swell is well balanced between NE at 35.9%, ENE at 33.8%, NNE at 15.6%, N at 3.2% and NNW at 2.6%. This is a solid distribution for Margara because the NE/NNE swell hits the north-facing beach at a much more usable angle than the summer ENE slop. Waves in the 5-6.5ft (1.5-2m) range are frequent, and there are plenty of pulsing 6.5-8ft (2-2.5m) sets. The main problem in December is wind: ideal offshore wind is only present 30% of the time, the lowest of the year, with E at 37.2% and ENE at 32.3% dominating. When the wind does swing around to the south and southwest, Margara can fire with punchy, powerful winter surf. Air temperature averages 25.5°C, water is 27.4°C, and rainfall is lower at 2.37 mm/day.
