March is a cold month even though it starts the spring season in Wyoming. Day high temperatures average 35°F (1.7°C) to 50°F (10°C) across different regions of the state. The Big Horn Basin, especially its lowest parts as well as the lower elevations of the northeast and eastern parts of the state, are warmer compared to the rest of the state. March seldom registers more than 1" (25mm) of rain in most areas, but snowfall touches fair numbers - northwest Wyoming averages 15" (381mm), while the southeast laps up 10" (254mm) to 15" (381mm), with the remaining areas in between 5" (127mm) to 10" (254mm). Average low temperatures are well below freezing such as 14°F (-10°C) in South Pass City, 20°F (-6.7°C) in Devils Tower and 22°F (-5.6°C) in Casper. March seems more like the tail of winter than the arrival of spring, with the sun still not making a regular presence on the horizon. By the end of March, tourists can also experience the start of the growing season in many places in Wyoming. Be sure to pack warm clothes, as the weather is still cold!
