The NOAA 1991–2020 climate normals describe Mullan Pass Vor/dme, Idaho as a location with an annual average temperature of 39°F, ranging from a mean daily high of 45°F to a mean daily low of 32°F. July is typically the warmest month of the year, while December is the coldest. These thirty-year averages, computed from station USW00024154, 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. Mullan Pass Vor/dme receives roughly 45.1 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near June 10 and the first fall freeze near September 23. For energy use, 9,714 heating degree days and 102 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Mullan Pass Vor/dme 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 July-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.
