What Dillon U OF Montana Western's climate means for you
Dillon U OF Montana Western runs 43°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.

July is typically the warmest month of the year, while December is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.

Dillon U OF Montana Western receives roughly 11.3 inches of precipitation each year, with 11.2 inches typically falling as snow. The frost-free season averages 100 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near June 5 and the first fall freeze near September 13. For energy use, 8,176 heating degree days and 116 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Dillon U OF Montana Western scores 44/100 (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.
