The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 30, short of 90°F on every date, while 207 dates carry a normal low at or below freezing, the coldest 14°F near December 24.
The freezing stretch
The normal low stays at or below 32°F into May 7, then returns to freezing around October 14, covering 207 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
August 10 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Data-derived climate profile
How Adel's climate pattern fits together
heating led · mid swing
Adel's energy balance leans toward cold weather: 8,627 annual heating degree days against 82 for cooling. Its 38.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 100 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and December mark the typical warm and cold ends of the calendar in Adel's middle-range seasonal profile. The measured spread is 38.2°F. The annual average is 42°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Adel'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 Adel'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 Adel, 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 Adel's primary station: ADEL (USC00240056). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Adel; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Adel 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.
