Newfoundland and Labrador is home to a variety of climates and weather. One of the main reasons for this diversity is the geography of the province. The island portion of the province spans 5 degrees of latitude, which is comparable to that of the Great Lakes. The province has been divided into six climate types, but in broader terms Newfoundland has a cool summer subtype of a humid continental climate, which is greatly influenced by the sea since no part of the island is more than 100 km from the ocean. Northern Labrador is classified as a polar tundra climate, southern Labrador has a subarctic climate.
Subarctic climate (Köppen climate classification Dfb) - long, usually very cold winters, and short, cool to mild summers.
