🌡 The weather here, in general

Cheyenne gets a real winter. February nights average 19°F, and July highs reach about 83°F — a 64-degree swing across the year. Cold that deep is its own hazard: exposed skin, car batteries and water pipes all have opinions about it.

Genuinely hot days are uncommon — about 8 a year reach 90°F. That is precisely why they catch people out: air conditioning is far from universal in a place that only needs it a fortnight a year.

Snow is a real feature of the year: roughly 47 inches falls in an average year, mostly across January, February, March, April, May, October, November and December. With 152 nights a year at or below freezing, ice on the roads is a longer season than snow on the ground.

Rainfall averages about 17 inches a year, wettest in May and driest in January.
