Climate Insight: Kemmerer, WY
An annual average temperature of 39°F, ranging from a mean daily high of 55°F to a mean daily low of 22°F is what the NOAA 1991–2020 climate normals report for Kemmerer, Wyoming. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00485105 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Anyone planning to live, garden, or travel in Kemmerer should weigh precipitation alongside temperature: the annual average runs 9.4 inches, with 49.7 inches typically falling as snow. Growing-season length varies with elevation and microclimate. And on the energy front, 9,695 heating degree days and 50 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Kemmerer scores 32/100 (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.
