The Mountains and Basins region experiences one of the most arid climates in all of Texas. Low rainfall, intense sunshine, and extreme temperature swings define daily and seasonal life here.

• Annual rainfall averages less than 12 inches in most of the region

• Summer temperatures frequently exceed 100°F on the desert floor

• Winters can bring freezing temperatures and occasional snow at higher elevations

• Low humidity and strong winds accelerate evaporation and drought conditions

• The rain shadow effect of mountain ranges intensifies dryness in the basins below
