Although Eastern Ontario is situated in Canada, which has a reputation for being very cold, Eastern Ontario is in the "Long Summer/Short Winter" belt of Southern Ontario and Southwestern Quebec, which is the only part of Canada in which the summer is significantly longer than the winter. Summers in Eastern Ontario usually last about 5-6 months long, and winters are about 4-4 1/2 months long. Autumn and spring are very short (especially Autumn).
The first snowfalls of the year usually occur in mid-to-late November, but snow doesn't actually cover the ground until December. Before that, snow usually melts as soon as it hits the ground.
In the spring, the snow usually starts melting in March, although occasional "warm breaks" with temperatures as high as 10°C (50°F) usually occur once or twice in January and February.
In recent years, winters have gotten much warmer, so often in the winter freezing rain will occur, when it is not warm enough for rain but not cold enough for snow. Freezing rain is basically raining ice pellets, which makes driving very hazardous and often closes down schools and makes the roads very icy for a few days.
In the summer, humidity is often common, especially in July. Although temperatures are usually just under 30°C (86°F), humidity can make the temperature feel like its about 38°C (100°F). Humidex temperatures have even been known to reach 45°C (113°F).
