Learn About Colorado's Climate

There are so many variables that make the climate of Colorado exciting to study and challenging to predict! Being located in the middle latitudes is ideal for experiencing active weather patterns year-round. Colorado's interior continental location, combined with complex topography, results in dramatic climate differences from place to place and from year to year. Colorado is also known as a "Headwater" state - with some of the highest elevations in the United States located near and along the Continental Divide, waters for 4 major river basins begin within our borders! Combine all these complicated factors, and a fascinating and diverse climate for each corner of the state emerges.
