Colorado Weather

Colorado Home | Colorado Sitemap

Colorado, for the most part, has a cool, bracing climate. During summer it is sometimes hot during the day on the plains, a heat that is often relieved by afternoon thundershowers. The mountain regions are almost always cool. Humidity is usually low so that the climate is relatively comfortable even on hot days. Colorado’s thin atmosphere allows greater penetration of solar radiation, resulting in pleasant daytime conditions even during the winter.

The climate of local areas is profoundly affected by differences in elevation, and extreme variations occur within short distances. While temperature decreases and precipitation generally increases with altitude, such patterns are modified by the orientation of mountain slopes with respect to the prevailing winds, and by the effect of other topographical features in regards to creating local air movements.

Thunderstorms are quite prevalent in Colorado and can become very severe. Tornadoes are almost unheard of in the mountains or in the west and are relatively rare over the eastern plains. Other severe storms include the blizzards of the eastern plains and the heavy snows in the high mountains that create the danger of avalanches.
