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
Summer temperatures average 68.6°F, with only 23 days reaching 90°F or hotter—well below the state's heat-prone counties. Winters average 29.8°F with 56.3 inches of snow annually, making Montezuma one of Colorado's snowier counties outside the high peaks.
Prepare for snow and moderate heat swings
Residents should invest in reliable winter gear and snow removal equipment given 56+ inches of annual snowfall. HVAC systems need to handle both heating (sub-freezing winters) and cooling (occasional 90°F summer days), making a dual-system setup sensible for comfort and efficiency.
