April weather forecast
Wyoming, USA

April ushers in more noticeable changes in Wyoming’s climate, paving the way for spring’s arrival. Average low temperatures experience a moderate rise, settling between 20°F (-6.7°C) and 30°F (-1.1°C) across various regions and elevations. Snowfall becomes less frequent, especially in the plains where accumulations reduce to approximately 10" (254mm). The highlands, however, can still receive up to 50" (1270mm) of snow, catering to the tail end of the winter sports season.

When compared to March, April sees a significant warming trend, and the days become progressively longer. The persistent winds across Wyoming's plains begin to temper, making outdoor activities more enjoyable. Chinook winds, though infrequent, still have the potential to bring brief periods of warmth. Despite the improving conditions, April’s weather remains somewhat unpredictable, with occasional late-season snowstorms or sudden temperature drops. The month marks a transition phase where winter loosens its grip, paving the way for the more inviting climate of late spring and summer, although the state's tourism industry has yet to experience a surge.
