Casper: Geography and Climate

At almost a mile above sea level, Casper rests at the foot of Casper Mountain and follows the contours of the North Platte River. With the Laramie Mountain Range of the Rocky Mountains to the west and the Wyoming plains to the east, Casper has been uniquely situated between natural resources for energy and outdoor adventure exploration on the one hand and agricultural endeavors on the other.

Casper sits within the area characterized by the National Weather Service as the "comfort zone," with year-round low humidity moderating the cold of winter and the heat of summer. Casper averages 275 days of sunshine every year and experiences an average wind speed of 12.9 miles per hour. The city's location and climate make it a jumping-off point for outdoor adventures.
