April: Ice-Out and Flat Patience
April is when the winter windswell machine starts to shut down. The average wave height falls to 0.4m (1.3ft) and the period drops to 3.3s, and although the wave directions are still dominated by NNW (17.1%), NW (16.1%) and WNW (15.7%), nearly all of that energy is below 0.5m (1.5ft). The lake is beginning to stratify, cold fronts are weakening as the jet stream lifts north, and fetch lengths over Georgian Bay are no longer enough to build anything substantial. Any wave from the W/WNW/NW/NNW quadrant is windswell, short and weak.
Wind conditions are still wintry: onshore directions blow 48% of the time, while offshore E/ESE/SE/SSE winds appear 24% of the time. Yet with 0% ideal surfing windows and an average swell height barely registering, Wasaga is effectively flat. Air temperatures warm to 4.3°C, precipitation increases to 1.92 mm/day, and water temperatures begin to move from winter freezing toward 3-6°C (37-43°F). Keep your wetsuit thick and your expectations low.
