Climate Insight: Cottonwood, ID

The NOAA 1991–2020 climate normals describe Cottonwood, Idaho as a location with an annual average temperature of 48°F, ranging from a mean daily high of 57°F to a mean daily low of 38°F. August is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USC00102159, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Cottonwood receives roughly 22.6 inches of precipitation each year, with 61.4 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 6 and the first fall freeze near October 13. For energy use, 6,718 heating degree days and 393 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Cottonwood scores 57/100 (Moderate), 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 August-driven heat, or deep winter for December-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.
