Our dataset lists 204 places in Wyoming; the 1 above has a page. For a smaller town, the nearest city above is the closest match.

The July figure is that city’s 1991–2020 normal mean temperature, rounded to the nearest degree — NOAA NCEI station normals from the nearest station where one covers the city, otherwise modelled normals (EC_Earth3P_HR via Open-Meteo); each city page names which.
