Data-derived climate profile
How Rock Springs's climate pattern fits together
heating led · mid swing
Rock Springs's energy balance leans toward cold weather: 7,217 annual heating degree days against 548 for cooling. Its 52.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Rock Springs's frost-free season lasts about 179 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Rock Springs's middle-range seasonal profile. The measured spread is 52.5°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Rock Springs's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Rock Springs's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Rock Springs, not an official NOAA class or a year-ahead forecast.
