Warming context for Cimarron

Methodology

The chart below traces how the U.S. land temperature anomaly has moved against the global mean since 1900. For Cimarron, the NOAA 1991-2020 normal captures average conditions across that spread - notably, the most recent decade runs warmer than the 30-year mean itself.

Climate Insight: Cimarron, CO

Based on station USC00051609 feeding NOAA's 1991–2020 climate normals, Cimarron, Colorado averages 43°F a year, ranging from a mean daily high of 61°F to a mean daily low of 25°F. July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.

Anyone planning to live, garden, or travel in Cimarron should weigh precipitation alongside temperature: the annual average runs 14.3 inches, with 66.7 inches typically falling as snow. The frost-free season averages 82 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near June 20 and the first fall freeze near September 10. And on the energy front, 8,090 heating degree days and 87 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Cimarron scores 34/100 (Below Average), 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 January-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.
