Colorado has a diverse climate. The variation is due mostly to the geographic makeup of Colorado as mountains and valleys play a large role in the kind of weather a region experiences. The Eastern Plains region has largely a semiarid climate, but to the west the climate is more uncertain.
The Eastern Plains region's static climate consists of low humidity, plentiful sunshine and little precipitation year round. Western Colorado's climate can vary significantly within short distances of a few miles. The difference between Pike's Peak and Las Animas, 90 miles away, is about the equivalent climate difference as Iceland and Florida. In general, precipitation increases and temperature decreases as elevation climbs.
