About Chaffee County Weather

Chaffee: High alpine chill and dryness

Chaffee County averages 45.5°F annually, running 0.5 degrees cooler than the U.S. median of 46°F. Despite receiving only 9.3 inches of precipitation yearly, the county's 43 inches of annual snowfall reflects how elevation transforms modest moisture into significant winter precipitation.

Cooler mountain interior

At 45.5°F, Chaffee ranks slightly below Colorado's state average of 46°F, reflecting its Arkansas Valley location and elevation. The county represents the state's mountain-interior cool zone, warmer than high peaks but cooler than front-range lowlands.

Valley position creates temperate middle

Chaffee (45.5°F) sits between Alamosa County's alpine cold (42.5°F) and the Front Range warmth of Adams County (50.7°F). Its Arkansas Valley location provides moderation between extremes.

Extreme cold, sparse rainfall

January averages 26.6°F while July peaks at 66.8°F, with just 10 days per year reaching 90°F. Annual snowfall of 43 inches proves that elevation transforms low precipitation (9.3 inches) into meaningful snow accumulation.

Alpine heating, snow management

Residents need heavy-duty heating systems for sustained cold and winter months lasting September through May. The 43 inches of annual snowfall requires robust removal equipment and seasonal planning; cooling needs are minimal with only 10 annual heat days.
