Santa Fe enjoys a semi-arid climate. Due to the 7,000 ft. elevation, summers are extremely mild with warm sunny days and cool breezy nights. Air conditioning in Santa Fe is seldom necessary. Because of Santa Fe's location nestled between the Sangre de Cristo Mountains to the east, and the Jemez Mountains to the west, winters are usually mild, although the nights can go down below freezing at times. The low humidity and clear blue skies free from smoke and smog make the Santa Fe climate one of the healthiest in the United States. Just check out this article: Santa Fe Chosen as Healthiest City!
