Cheyenne Weather, When to Go and Climate Information

(Cheyenne, Wyoming - WY, USA)



Along with the entire state of Wyoming, the capital of Cheyenne enjoys a semi-arid climate, with a fairly lengthy and cold winter season, followed by more settled, warmer summer weather.

Even on the coldest of days, unexpected spells of warmer temperatures can arrive, thanks to the Chinook winds and high pressure blowing down from the neighboring Rocky Mountains. This means that daytime temperatures can hover around 10°C / 50°F at times in December, January and February, although temperatures regularly drop below freezing by night.

Snowy weather often makes an appearance in Cheyenne, with surprisingly high levels of snowfall as late as March and April. However, that said, even the heaviest snowfall soon melts and rarely lasts for more than a few days.


Seasonal Climate Variations / When to Go

By the time that late April arrives in Cheyenne, the climate is beginning to change, with spring being well and truly on its way. Warmer weather, longer days, fresh leaves on the trees, cheaper accommodation and a lack of tourists all make this season a great time to visit the state capital.

The summer months see the busiest time in Cheyenne, with the city enjoying its warmest climate and highest visitor levels. Even though precipitation levels rise between May and August, the high temperatures and days of sunshine mean that there is usually plenty of good weather to go around, rarely spoiling a vacation here. July and August are especially hot, when temperatures peak at 27°C / 81°F, 28°C / 82°F or even higher.
