Climate
The Toronto region experiences a cycle of beautifully contrasting seasons. Winters are not as cold and snowy as in most Canadian cities. Highlands to the north and west of the Greater Toronto Area absorb the brunt of winter storms and the waters of Lake Ontario moderate temperature extremes. However, there is enough snowfall to make for picturesque winter scenery in the countryside. Skiing and other winter sports are popular and easily accessible.
Spring is occasionally rainy, culminating in a dramatic outburst of budding and flowering. Summers are usually warm and dry, with a few weeks of hot weather in late July or early August.
The region is at its most beautiful in the Fall. After a brief cooling period, a warm “Indian Summer” arrives and splendid Autumn hues appear before winter sets in. Even the urban areas are dense with colorful maples and many other common variety trees that burst into color. Winter weather usually returns around mid-December.
