Climate Insight: Jackson, MT

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.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Jackson receives roughly 11.9 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate. For energy use, 10,280 heating degree days and 13 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Jackson scores 47/100 (Moderate), 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 December-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.
