Climate Insight: Tarkio, MO
An annual average temperature of 51°F, ranging from a mean daily high of 62°F to a mean daily low of 41°F is what the NOAA 1991–2020 climate normals report for Tarkio, Missouri. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00014945 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Beyond temperature, Tarkio averages an uncharted amount of precipitation annually, predominantly as rainfall - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 179 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 19 and the first fall freeze near October 15. Turning to energy use, 6,051 heating degree days and 1,009 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Tarkio scores 49/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
