Conditions at Wasaga Beach in December
December: Maximum Winter Windswell
December is the most consistent month of the year for wave energy at Wasaga Beach. Average wave height peaks at 0.7m (2.5ft) along with January and February, and the average period holds at 4.0s. The wave rose is again dominated by the NW quadrant - NNW 16.4%, W 10.5%, NW 10.2%, WNW 9.1% - and the occurrence of rideable 1-1.5m (3-5ft) and 1.5-2m (5-6.5ft) waves is at its annual high. These waves are generated by strong arctic fronts and Colorado/Alberta lows that cross the Great Lakes, producing a solid, choppy windswell that breaks along the beach. It is raw and unruly, but it is surf.
The final piece of the puzzle is wind. December offers the highest ideal surfing percentage of the entire year at 6%, thanks to frequent continental highs that park over the southeastern U.S. and provide offshore E/ESE/SE/SSE drafts between systems. Onshore W/WNW/NW/NNW flow is about 35%, the lowest of the winter. Air temperatures average -2.9°C, precipitation runs near 1.72 mm/day, and water temps hover around 2-5°C (36-41°F). If you can handle the cold, December often produces the best combination of size, wind and frequency of any month.
