Spring: Windy and Hail-Prone

Spring in Cheyenne means wind and the rainiest stretch of the year runs from May through July, driven by afternoon thunderstorms that can bring hail. This is also when Cheyenne's reputation as one of the windiest cities in the U.S. is most noticeable day-to-day.

Summer: Warm Days, Cool Nights

July is Cheyenne's warmest month, with an average high around 84°F warm, but rarely brutal, and summer wind speeds (around 10 mph on average) are actually lower than winter's. Big daily temperature swings are normal here, so evenings can cool off noticeably even after a hot afternoon.

Fall: The Transition Season

Fall brings a gradual cooldown from summer highs back toward winter's cold, with wind picking back up as the season progresses. It's generally considered one of the more comfortable stretches of the year for outdoor activities, before winter prep becomes a priority again.
