About Montrose County Weather
Montrose slightly warmer, drier than US norm
Montrose County averages 48.2°F annually, edging above the U.S. median of 47.5°F, while its 14.0 inches of precipitation falls well below the national average of 38 inches. This dry, temperate profile reflects high-elevation high-desert geography typical of western Colorado.
Upper-middle warmth in Colorado rankings
At 48.2°F, Montrose ranks in Colorado's warmest third of counties, running 2.2°F above the state average of 46.0°F. It sits slightly cooler than neighboring Montezuma but remains well above the state's frigid high-mountain counties.
Comparable to Montezuma, hotter than Ouray
Montrose (48.2°F) sits just 0.6°F below Montezuma County (48.8°F), making them regional climate twins. Both run dramatically warmer than Ouray County (44.5°F) to their south, which gains elevation and vastly more precipitation.
Hot summers, cold winters, sparse snow
Summer temperatures average 68.9°F with 36 days of 90°F-plus heat—notably higher than Montezuma's 23 days, signaling a sunnier climate. Winters average 27.7°F with just 31.3 inches of snow, making it one of Colorado's driest counties year-round.
Manage heat and drought-conscious landscaping
With 36 extreme heat days annually and only 14 inches of rain, residents should prioritize air conditioning maintenance and drought-tolerant outdoor design. Minimal snowfall (31 inches) means less shoveling but requires preparedness for occasional winter storms and roof load surprises.
