Conditions at Kincardine in December
December: Winter Swell Engine
December is Kincardine's peak-energy month by average height and period: around 4ft (1.3m) at 5.1s. The swell rose is a winter classic, with W (10.8%), NW (10.7%), WNW (9.4%), WSW (7.7%) and NNW (12.3%), giving the exposed west-northwest beach the most consistent shot at rideable, punchy windswell. Strong pressure gradients and Arctic cold fronts constantly kick up large stretches of Lake Huron, and early-winter ice is still limited enough to allow ample fetch.
Winds are largely onshore, with WSW (10.8%), W (10.5%), WNW (7.9%), NW (7.1%) and NNW (10.1%) leading the charge. Ideal surf wind is 4%, but the windows are more meaningful because the existing swell is bigger and the lake is still mostly open. With average air temperature at 0.6°C, precipitation of 1.91 mm/day and water temperatures near freezing, this is heavy-wetsuit, cold-hands surfing. December delivers the goods when the post-frontal sky clears and an offshore E-to-ESE breeze finally grooms the leftover west-northwest lines.
