April sees warm temperatures and moderate rain with the advent of the spring season in Colorado. The average high temperatures are generally in the warm 50°F (10°C) to 60°F (15.6°C), while nights are on the colder side in the 25°F (-3.9°C) to 41°F (5°C) across the state. April witnesses a bit of rain with an average of 1" (25mm) to 2" (51mm) in the state and is the last month of sizeable snowfall. Spring sees the early thawing of snow by mid-April in the lower plateau regions, while the mountaintops keep their icecaps intact for long periods. Lakes, springs, and rivers appear to be bubbling with freshwater as the snow starts to meltdown gradually. The sun shines for more extended periods and is regularly over the horizon for an average of 18 to 20 days in April. The floral blossoms cover the ground, and the awakened hibernating fauna is in a quest for searching food everywhere. Pack layers of warm clothing when exploring the high mountain trails as the nights are cold, and the climate is alpine at high altitudes.
