Data-derived climate profile
How Chillicothe Mound City's climate pattern fits together
heating led · mid swing
Chillicothe Mound City's energy balance leans toward cold weather: 5,145 annual heating degree days against 986 for cooling. Its 44.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Chillicothe Mound City's frost-free season lasts about 185 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 Chillicothe Mound City's middle-range seasonal profile. The measured spread is 44.4°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Chillicothe Mound City'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 Chillicothe Mound City'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 Chillicothe Mound City, 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 Chillicothe Mound City's primary station: CHILLICOTHE MOUND CITY (USC00331528). 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 Chillicothe Mound City; 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 Chillicothe Mound City 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.
