Early morning and evening there's deer, muskrat, coyote and great blue heron moving along the river's edge. Too warm for trout, the Colorado River supports the endangered Colorado Squawfish and the Humpback Chub. Weather is usually warm and sunny and very user friendly. In May and June the day temperatures are in the 90s, with days in the high 90s and low 100s common in July and August. Brief afternoon showers are very common.
Evenings are very comfortable, though cool in the spring and fall.
It is a very dry climate, so the heat is not the sweltering kind. Besides, the best part about being too warm is getting into the river to cool off.
