Conditions at Supertubes in December
December: Back to Summer Mode
December marks the return of summer conditions. Average swell height settles at around 6ft (1.9m) and the average period shortens to 11.9s. The swell train is again almost entirely from the SSW/SW quadrant, with SSW at 28.3 percent and SW at 40.6 percent, plus WSW at 7.7 percent. This produces consistent, rideable surf, but the shorter periods mean it lacks the heavy, maxed-out feel of the winter months. On the bright side, there is still plenty of groundswell in the mix for a summer surf break.
Wind patterns follow the summer playbook: SSE (20.1 percent) and S (19.8 percent) dominate, with SE (13.3 percent) and SSW (13.5 percent) close behind. Ideal offshore conditions are 18 percent, usually early in the morning before the sea breeze kicks in. Air temperatures average 19.2°C (12.8-28.6°C), water warms to 19.9°C, and precipitation is low at 0.42 mm/day. Bring a shortboard or even a fish, and get out early.
