The Mixedwood plains have relatively wet, warm, summers and cool, snowy, winters. It also has a mild climate and abundant rainfall. The city is known for its cold winters, but its summers are hot and generally sunny, with rare muggy days. This moderation in weather is caused by the nearby bodies of water (the Great Lakes). The Mixedwood plains also have a wide variety of growing seasons with about 1750-2500 growing degree days above 5°C. Average temperatures vary from 10 to 25°F (-13° to 5°C) in January to 65-80°F (18°-27°C) in July. This ecozone also has an annual precipitation of about 720-1000 mm. The weather in this ecozone changes rapidly, due to it lying in one of North America’s major storm tracks. One thing worth knowing is that Montreal begins snowing in late November and while rapidly removed from sidewalks and roads, snow heaps up everywhere else and remains part of the landscape until it begins to retreat sometime mid-March.
