Conditions at Curl Curl in December
December: Full Summer Mode
December rounds out the year in full summer mode, and quality is at a premium. Average swell drops to just under 5ft (1.5m) and the period is only 8.3s, placing most days in the average, punchy but short-period bracket. The swell window is still full, with SSE (18.3%), ENE (16.7%), SE (15.1%), E (13.5%), ESE (13.1%), NE (8.8%) and S (8.5%), yet the wind distribution is heavily weighted toward NE (14.5%), NNE (10.8%), ENE (11.0%), SSE (10.6%) and S (10.6%). Ideal offshore winds are present just 23% of the time. Water warms to 21.5C and air averages 21.2C, while rainfall averages 2.43mm/day. Surfers can still score fun, rippable waves in the morning before the sea breeze builds, but the afternoon almost always adds chop. If an East Coast low organizes north of the corner, December can fire, but the consistent, high-quality windows of autumn and winter are still a few months away.
