Wyoming IS Cold But Let’s See Weather Data For Cheyenne
We like to talk of how cold winter can be in Wyoming, but let’s look at some weather data for its Capitol City, Cheyenne.
On the Wikipedia page for Cheyenne, Wyoming, scrolling down to “Climate,” you’ll find a long version of the following. (Summer data edited.)
Winters are cold and moderately long, but relatively dry – not as cold as when humid. Cheyenne averages well below 60 percent relative humidity year round.
Cold is also interrupted often with chinook winds from the mountains that can bring the high above 50° on twenty days from December to February. We're just glad they didn't mention wind in general.
Snowfall is greatest in March and April, yet thick snow cover rarely stays. Annual precipitation of 15.9 inches tends to be concentrated from May to August and is low during fall and winter. (Yay!)
The city of Cheyenne gets an average 2,980 hours of sunshine annually. That’s 67% of the possible total, or only 121 cloudy days. (And have you ever heard that the suns ultra violent rays are 5 percent more intense per 1000 feet about sea level? With an altitude of 6000, Cheyenne’s UVs are 30 percent warmer.)
Most of that information just doesn’t read so brutally cold as we can make our whole state seem. We have a few regions for different "degrees" of winter weather.
