Climate Insight: Manderson, SD
An annual average temperature of 48°F, ranging from a mean daily high of 61°F to a mean daily low of 36°F is what the NOAA 1991–2020 climate normals report for Manderson, South Dakota. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00395154 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Manderson should weigh precipitation alongside temperature: the annual average runs an uncharted amount, predominantly as rainfall. The frost-free season averages 148 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 9 and the first fall freeze near October 4. And on the energy front, 6,830 heating degree days and 763 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Manderson 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.
