Andrews County is one of the principal geological areas of Texas. Early in geological history, perhaps 250 million years ago, a mountain range extended from southwest to northwest across central Texas. In the northwest, a shallow sea covered much of the state. This western area now is known as the Permian Basin. The basin of the former sea dips downward to the west from the north-central part of Texas, with its low point in the vicinity of Midland County, located southeast of Andrews County; then rises in elevation towards the northwest across Andrews County.

Andrews County has a cool-temperature, dry steppe climate characterized by mild winters. The average annual precipitation in the county is 15.40 inches. Approximately 84% of this amount falls during the warm season, April through October. Rains occur most frequently as the result of thunderstorms, and monthly and annual amounts are extremely variable. The warm season averages 213 days.

The vegetation in Andrews County consists mainly of mesquite, catclaw, and sand shinnery, which exists in abundance in most areas. Volunteer trees and ground cover are scarce due to the low amount of annual precipitation.
