Climate Insight: Greeley Unc, CO

The NOAA 1991–2020 climate normals describe Greeley Unc, Colorado as a location with an annual average temperature of 52°F, ranging from a mean daily high of 67°F to a mean daily low of 37°F. July is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00053553, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Greeley Unc receives roughly 14.7 inches of precipitation each year, with 34.9 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 2 and the first fall freeze near October 8. For energy use, 5,580 heating degree days and 895 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Greeley Unc scores 52/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for December-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
