What Fontenelle Dam's climate means for you
Fontenelle Dam runs 38°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
The NOAA 1991–2020 climate normals describe Fontenelle Dam, Wyoming as a location with an annual average temperature of 38°F, ranging from a mean daily high of 55°F to a mean daily low of 22°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00483396, 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. Fontenelle Dam receives roughly 7.5 inches of precipitation each year, with 26.5 inches typically falling as snow. Growing-season length varies with elevation and microclimate. For energy use, 9,854 heating degree days and 109 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Fontenelle Dam scores 32/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings January-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
