Warming context for Columbus

Methodology

Columbus's NOAA 1991-2020 normal sits inside a longer story: U.S. land temperatures have been tracking (and drifting from) the global mean since 1900, and the chart below shows that spread, with the most recent decade running warmer than the 30-year mean.

Climate Guides

Climate Insight: Columbus, MT

An annual average temperature of 44°F, ranging from a mean daily high of 60°F to a mean daily low of 29°F is what the NOAA 1991–2020 climate normals report for Columbus, Montana. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00241938 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Columbus receives roughly 15.5 inches of precipitation each year, with 47.6 inches typically falling as snow. The frost-free season averages 110 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 27 and the first fall freeze near September 14. For energy use, 7,736 heating degree days and 241 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Columbus scores 39/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings January-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
