The year, day by day
Stilwell works both ends of the calendar. Normal highs climb to 91°F by July 29 and hold at or above 90°F on 35 dates, then normal lows drop to freezing or below on 68 dates, bottoming at 26°F around January 11.
When the heat sits
Normal highs reach 90°F from July 14 through August 17, covering 35 dates. The broader mild season, normal highs of 70°F or more, runs April 9 to October 22.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into February 14, then returns to freezing around December 9, covering 68 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
April 8 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Data-derived climate profile
How Stilwell's climate pattern fits together
heating led · mid swing
Stilwell's energy balance leans toward cold weather: 3,629 annual heating degree days against 1,506 for cooling. Its 41.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Stilwell's frost-free season lasts about 218 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 Stilwell's middle-range seasonal profile. The measured spread is 41.2°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Stilwell'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 Stilwell'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 Stilwell, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Stilwell's primary station: STILWELL 5 NNW (USC00348506). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 4070350). Match rule for Stilwell: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Stilwell comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
