Wyoming’s Wettest Novembers Since 1895

Tracing Wyoming’s Wettest Novembers Back to 1895

Stacker compiled a ranking of the Novembers with the most precipitation in Wyoming since 1895 using data from the National Centers for Environmental Information. Rankings rely strictly on the highest total precipitation recorded for each respective month.

Weather records across Wyoming reveal notable swings in late-autumn moisture spanning more than a century. While standard autumn patterns across the region often lean dry and crisp, historical climate tracking demonstrates occasional severe weather saturation. Examining these past months provides clear context for how extreme precipitation interacts with typical late-fall temperature drops.

At the top of the historical ledger stands November 1942, capturing the number one spot with a statewide total precipitation of 2.4 inches. That month brought an average temperature of 29.6°F, with state-wide highs reaching 40.6°F and lows dipping to 18.7°F.

November 1983 Claims Second Spot for Historical Precipitation

The historical record features several notable ties and closely clustered precipitation totals across decades of observation. Right behind the peak month, November 1983 secured the second spot with 2.32 inches of precipitation, accompanied by an average temperature of 28.5°F, a monthly high of 38.2°F, and a low of 18.8°F.

Moving further down the compiled list, earlier winters and autumns registered significant moisture levels under sharply colder conditions. November 1896 recorded 2.21 inches of precipitation with a frigid average temperature of 19.4°F, peaking at 30.1°F and bottoming out at 8.7°F. Meanwhile, November 1985 brought 1.96 inches of precipitation alongside a statewide average of just 19.1°F, with extremes ranging from a high of 28.8°F down to a low of 9.3°F.

Broader Regional Climatic Comparisons

Similar state-level climate data compilations for neighboring regions put Wyoming’s figures into perspective. In Nevada, historical tracking analyzed by Stacker demonstrates that November 1960 had 2.21 inches of precipitation. Both states illustrate how rare late-autumn storms can dramatically alter baseline seasonal moisture averages.

Understanding these historical precipitation ceilings helps researchers track long-term meteorological shifts across the Mountain West. As federal monitoring agencies continue to update state-by-state climate indices, each new season adds another data point to records that stretch back to the late nineteenth century.
