December: Winter's Cleanest Angles

Nearly 70 percent of the waves arrive from the SW, WSW and W corridor, and the average height sits at 1.2m (4ft) with a 13.4s period. This is quintessential winter surf: organized, long-period groundswell hitting the west-facing bay with minimal southerly contamination. Wind is moderate, with ideal conditions 39 percent of the time and many crisp north-northeast to east land-breeze mornings. It is one of the driest months of the year at 0.18 mm/day, air temperatures stay pleasant around 25°C, and water remains a comfy 28.7°C -- a stellar finisher.
