Climate Guides
Climate Insight: Jackson, WY
Based on station USC00484910 feeding NOAA's 1991–2020 climate normals, Jackson, Wyoming averages 38°F a year, ranging from a mean daily high of 52°F to a mean daily low of 24°F. July is typically the warmest month of the year, while January 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.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Jackson sees about 17.6 inches of precipitation a year, with 78.2 inches typically falling as snow. Growing-season length varies with elevation and microclimate. On the energy side, 9,857 heating degree days and 22 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 37/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings January-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
