Climate
Weather Conditions Lake Huron and Georgian Bay modify the temperatures in the surrounding shores, dramatically affecting the climate of Collingwood. The "Lake Effect" generally causes cooler temperatures along the shores of the lake during summer and milder temperatures in the winter. The overall moderating effect is that there are more frost-free days than what is found at similar latitudes (Collingwood average: 149 days). Another key aspect of the "Lake Effect" is the amount and type of snowfall experienced in areas around the lake during the winter months. Brief, blinding snow squalls are punctuated intermittently by periods of brilliant sunshine. The snowfall extends only 30-40 km inland. Areas close to the lakes, such as Collingwood, may experience heavy snowfalls, but inland areas seem to escape the brunt of these storms.
