Conditions at Wilderness in December
December: Summer Doldrums
December closes the year in the summer doldrums. ESE again tops the wind table at 19.3%, with SE at 11.6%, E at 9.4%, and S/SSW just under 8% each. Offshore flow sits around 5%, and the average swell height and period are flat, so the ideal-surfing score is 0%. Water temperature is 19.4°C, air averages 20.0°C, and rain is 1.24 mm/day. The coast is perfect for holiday swimmers, but surfers should keep their expectations low: the odd S/SSW groundswell can still sneak through, but it will almost always be accompanied by warm, onshore ESE winds. If a rare dawn offshore window appears, take it.
