About Park County Weather
Park is Colorado's coldest, mountain-locked county
Park County's 38.2°F annual temperature ranks as Colorado's coldest and sits 9.3°F below the U.S. median of 47.5°F. Its 13.9 inches of precipitation fall short of the national average, but elevation-driven snowfall dominates, making it an extreme high-altitude environment.
Single coldest county in all Colorado
At 38.2°F, Park County registers as Colorado's coldest county by a significant margin, running 7.8°F below the state average of 46.0°F. Only Pitkin County approaches its freeze profile, and both dominate Colorado's alpine climate tier.
Frigid fortress among Colorado's mountains
Park (38.2°F) sits 6.3°F colder than Ouray (44.5°F) and 14.8°F colder than Montezuma (48.8°F), making it a true polar outpost. Its elevation and mountain positioning create unmatched cold intensity within the state's already-chilly county network.
Zero extreme heat days, brutal winters, relentless snow
Park County records zero days above 90°F annually—the only Colorado county with this distinction—while summer averages just 57.0°F. Winter plummets to 19.6°F with 66.0 inches of snow, creating a perpetual deep-freeze environment above 10,000 feet.
Survival-grade heating and constant snow prep
Residents must maintain industrial heating systems designed for sub-zero temperatures and 66+ inches of annual snowfall. Outdoor living ceases in winter; summer recreation windows are narrow and weather-dependent, making season-specific equipment and emergency preparedness absolute necessities.
