Saskatchewan (/səˈskætʃəwən, sæ-, -wɒn/ (About this soundlisten)) is a prairie and boreal province in western Canada, the only province without a natural border. It has an area of 651,900 square kilometres (251,700 sq mi), nearly 10 percent of which (59,366 square kilometres (22,900 sq mi)) is fresh water, composed mostly of rivers, reservoirs, and the province's 100,000 lakes.
Saskatchewan is bordered on the west by Alberta, on the north by the Northwest Territories, on the east by Manitoba, to the northeast by Nunavut, and on the south by the U.S. states of Montana and North Dakota. As of Q3 2019, Saskatchewan's population was estimated at 1,178,657. Residents primarily live in the southern prairie half of the province, while the northern boreal half is mostly forested and sparsely populated. Of the total population, roughly half live in the province's largest city Saskatoon, or the provincial capital Regina. Other notable cities include Prince Albert, Moose Jaw, Yorkton, Swift Current, North Battleford, Melfort, and the border city Lloydminster (partially within Alberta).
Saskatchewan is a landlocked province with large distances to moderating bodies of waters. As a result, its climate is extremely continental, rendering severe winters throughout the province. Southern areas have very warm or hot summers. Midale and Yellow Grass (both near the U.S. border) are tied for the highest ever recorded temperatures in Canada, with 45 °C (113 °F) observed at both locations on July 5, 1937. In winter, temperatures below −45 °C (−49 °F) are possible even in the south during extreme cold snaps.
