What Edgemont's climate means for you
Edgemont runs 44°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
An annual average temperature of 44°F, ranging from a mean daily high of 61°F to a mean daily low of 28°F is what the NOAA 1991–2020 climate normals report for Edgemont, South Dakota. July is typically the warmest month of the year, while January is the coldest. That baseline comes from 2 weather stations 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 Edgemont should weigh precipitation alongside temperature: the annual average runs 16.1 inches, with 36.2 inches typically falling as snow. The frost-free season averages 120 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 23 and the first fall freeze near September 20. And on the energy front, 7,990 heating degree days and 533 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Edgemont scores 39/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
