Montréal

Environment

Montréal has an inland climate. Temperatures in winter months are cold, averaging–3°C (23°F). With an annual snowfall of 214 centimeters (84 inches), Montréal receives more snow than Moscow. Temperatures rise to 11°C (52°F) in April or October. Summers can be hot. Average summer temperatures are 26°C (79°F).

Water quality in the St. Lawrence River has improved with the clean up of the Great Lakes. However, Montréal does not yet treat sewerage, creating major pollution problems. Portions of the downtown and older industrial areas are now derelict and unoccupied, providing a sharp contrast to adjacent renewed areas of the city. Prevailing winds bring pollution from Ontario and the American Midwest.
