Conditions at Balangan in December
December: The Monsoon Returns
December brings a sharp step backward as the NW monsoon reasserts itself over southern Bali. Average swell height drops to 5.2ft (1.6m) and period falls to 12.7s, while the swell direction remains SSW/SW -- 57.0% and 36.5% respectively. The wind, however, flips back to the bad side of the compass: W accounts for 28.1%, WSW for 19.0% and WNW for 9.3%, leaving ideal wind at just 29%. Rain increases to 7.59 mm/day, air temperatures warm to 27.9°C and water temperature is back up to 29.3°C. Expect a textured, bumpy surface and lower energy swell, with only occasional windows of lighter winds and longer-period leftover swell. December is the beginning of Balangan's quiet season -- not necessarily flat, but far from its brilliant dry-season self.
