April transitions the cold conditions to warm temperatures with the advent of spring in entire Wyoming. Day temperatures are usually in the warm 50°F (10°C) to 60°F (15.6°C), while nights are mild in the 35°F (1.7°C) to 45°F (7.2°C) across the state. April sees a bit of rain with an average of 1" (25mm) to 2" (51mm) in the state, which gradually progresses in numbers up to summer. Lakes and springs start to meltdown, and the sound and smell of freshwater are refreshing in the backdrop of the mountains. Snowfall tapers down everywhere, barring the high mountain ranges as the sun shines more regularly. There is much enthusiasm as the melting of snow provides a start to the fishing season along with kayaking and canoeing, especially in the canyons. It is not odd for travelers to come across bison, elk, or bighorn sheep in a quest to explore the wildlife as the weather warms up. Pack layers of clothing when exploring the high mountain trails that start to free up by late April.
