The NOAA 1991–2020 climate normals describe Hoover, South Dakota as a location with an annual average temperature of 44°F, ranging from a mean daily high of 59°F to a mean daily low of 29°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00393945, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Beyond temperature, Hoover averages 18.2 inches of precipitation annually, with 47.5 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 125 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 19 and the first fall freeze near September 21. Turning to energy use, 8,191 heating degree days and 517 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Hoover scores 39/100 (Below Average), 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.
