Canada Weather by Month

Canada, the second-largest country in the world by land area, spans nearly 10 million square kilometers and stretches from the Atlantic Ocean in the east to the Pacific Ocean in the west, and northward into the Arctic Ocean. Its vast and varied geography includes towering mountain ranges such as the Rockies, expansive prairies, dense forests, and thousands of lakes and rivers. It shares its southern border with the United States, and its northern reaches extend into the Arctic, where frozen tundra and ice dominate the landscape.

Canada is made up of ten provinces and three territories, each with its unique geographic features and climate. The southern regions, particularly near the US border, are more densely populated and tend to have a temperate climate, while the northern areas experience harsh Arctic conditions. The country’s vast size results in a wide range of climates, from the Pacific Northwest’s coastal rainforest to the cold, dry winters of the Prairies and the humid, warm summers of Ontario and Quebec.
