What Are the Warmest Cities in Wyoming?

In this article I’m going to share with you my ranking of the warmest places in Wyoming.

I created my list by researching data provided by the National Oceanic and Atmospheric Administration and other climate data providers.

Below I’m listing the top 10 warmest places in Wyoming that have the highest average yearly temperatures. Later in the article I share a table with 30 most populous cities in Wyoming.

Top 10 Warmest Cities in Wyoming

Warmest Wyoming Cities

Here are the top 10 warmest places in Wyoming ranked by their daily mean temperature. While the following ten cities have relatively similar average annual temperatures, the warmest place (Wheatland) is over 11 degrees warmer than the coldest town (Pinedale).

For the top five cities I also give average winter and summer temperatures.

1. Wheatland – daily mean temperature of 49 °F

The town of Wheatland in the southeastern part of the state is the warmest city in Wyoming, though the second warmest place (Basin) has almost exactly the same annual daily mean temperature. Wheatland has by far the highest average high temperature (65 °F) which means it features the hottest days out of all cities in this ranking.

The warmest town in Wyoming has the mildest winters, with average 43-45 °F during the day and 16-17 °F at night. In the summer, average daytime temperatures reach 83-90 °F. At night, they drop to cool 48-54 °F—the lowest nighttime temperatures in the summer on this list. Wheatland gets 18 days of snow with 40 inches of average annual snowfall a year.

Winter temperatures: highs of 43-45 °F, lows of 16-17 °F

Summer temperatures: highs of 83-90 °F, lows of 48-54 °F

2. Basin – daily mean temperature of 48.95 °F

Basin, a town located in the northern part of the state in the Bighorn Basin, has almost exactly the same daily mean temperature as Wheatland but it features much colder winters. Average highs are just 32-39 °F while lows drop to freezing cold 9-15 °F. The reason why Basin still ranks second is because it has very hot daytime temperatures during the hottest part of the year. They reach 84-93 °F during the day and drop to 55-60 °F at night.

According to weather data, Basin holds the record for the maximum temperatures registered in Wyoming (115 °F on August 8, 1983). It also has the highest recorded temperature in April and July.
