About Montezuma County Weather

Montezuma runs warmer than US average

At 48.8°F annually, Montezuma County sits above the U.S. median of 47.5°F, making it a genuinely temperate corner of Colorado. Its 15.5 inches of annual precipitation closely mirrors the national average, creating a semi-arid climate typical of the Southwest's high plateaus.

Warmest tier in Colorado's cool state

Montezuma's 48.8°F average ranks it in the warmest third of Colorado's 64 counties, sitting 2.8°F above the state average of 46.0°F. This makes it notably warmer than the state's mountain counties but cooler than Colorado's hot southeastern plains.

Warmer than nearby mountain rival Ouray

Montezuma County (48.8°F) runs 4.3°F warmer than its neighbor Ouray County (44.5°F), which sits higher in elevation and catches significantly more snow. It also outpaces Morgan County (49.0°F) by a fraction, though Morgan experiences far more extreme heat days at 58 versus Montezuma's 23.

Mild summers, manageable winters, moderate snow
