The Climate of Wyoming

By | August 27, 2022

According to Abbreviation Finder, the mainly mountainous Wyoming (WY) is one of the United States of America. The Rocky Mountains largely define the landscape of Wyoming, with peaks of more than 4,000 meters. At 4,207 feet above sea level, the summit of Gannett Peak is Wyoming’s highest point. The northeast and east of the state fall within the flat Great Plains region, where the landscape consists mainly of steppe and grasslands.

Arid Climate Types

The cold steppe climate is the most common climate type in Wyoming. In places where the amount of precipitation increases somewhat, there is a moderate continental climate. This applies, among other things, to some places in the mountain areas, where the annual precipitation sum is sometimes above five hundred millimeters. With only 200 to 300 millimeters of precipitation per year in most places, Wyoming is one of the driest states in America. In some places there is even a desert climate. The Bighorn Basin, for example, has a cold desert climate (type BWk) in the lowest areas, because only 130 to 200 millimeters per year are recorded there. Eastern Wyoming falls just inside Tornado Alley, a large area in the middle of the US that is prone to tornadoes.

Winters in Wyoming

The winter months in Wyoming are cool and pronounced winters, often creating excellent skiing conditions in the mountains. Within Wyoming you will find a number of winter sports areas where you can ski for a number of months. Sometimes you can hit the slopes as early as November, and if you’re lucky, Wyoming can ski or snowboard well into spring. Some parts of Wyoming have a winter that lasts up to 7 months. A good example of this is Teton Village, where you can ski from November until often in May. This ski resort is best known for its excellent off-piste skiing or snowboarding options.
