On average, annual precipitation is 250 mm/year (77–507 mm/year) and the mean annual temperature is 14.7°C (13.5–16.3°C). This ecoregion extends from within the United States south into Mexico.This desert is unique, as it has been sheltered from the influence of other arid regions such as the Sonoran Desert by the large mountain ranges of the Sierra Madres. The Chihuahuan Desert is located at the wettest end of the precipitation gradient.
