December keeps November's swell, 2.2 m at 12.5 seconds with wind workable seventeen days out of thirty, and pushes the weather trade one step further: 49 mm of rain across four days, the wettest month of the year, and 7.2 hours of sun a day, its lowest.
It is also where the grid narrows on levels. December is the only month of the year given to advanced and expert surfers on the main breaks: size and period together leave little margin on the points.
Water sits at 18 °C, air at 22 °C. Crowds and prices are high, with a spike from 20 December to 10 January during which camp rates climb noticeably.
