Conditions at Nyang Nyang in December
December: Monsoon Chaos Looms
December is where the low surf season at Nyang Nyang really sets in. The average swell size dips to 1.6m (5.2ft), the period drops to 12.7 seconds, and the swell distribution shifts back toward the west - SSW at 57.0%, SW at 36.5% and WSW at 3.6%. There are still plenty of 3-6ft (1-2m) waves, but the energy is less organized and the longer-period power of the dry season has faded.
Wind is the bigger problem. The northwest monsoon is active, with W at 28.1%, WSW at 19.0%, WNW at 9.3% and SW at 9.3%. Only 19% of the time falls into the ideal wind category. Rain is heavy at 7.59 mm/day, air temp is 27.9°C and water temperature is a warm 29.3°C. December is a waiting game. Keep an eye on the charts for a strong Southern Ocean low and a morning north to northwest offshore breeze; those are the rare windows that can turn a messy monsoon day into a surprisingly fun, uncrowded session at Nyang Nyang.
