Climate Insight: Altamont, UT
An annual average temperature of 42°F, ranging from a mean daily high of 56°F to a mean daily low of 29°F is what the NOAA 1991–2020 climate normals report for Altamont, Utah. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00420074 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. Altamont receives roughly 9.4 inches of precipitation each year, with 38.7 inches typically falling as snow. The frost-free season averages 115 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 31 and the first fall freeze near September 23. For energy use, 8,450 heating degree days and 182 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Altamont scores 29/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows, shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
