The freezing stretch
The normal low stays at or below 32°F into March 30, then returns to freezing around November 7, covering 145 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 1 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Data-derived climate profile
How Grant City's climate pattern fits together
heating led · mid swing
Grant City's energy balance leans toward cold weather: 6,201 annual heating degree days against 912 for cooling. Its 51.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Grant City's frost-free season lasts about 173 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 Grant City's middle-range seasonal profile. The measured spread is 51.7°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Grant 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 Grant 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 Grant 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 Grant City's primary station: GRANT CITY (USC00233369). 2 NOAA stations are mapped to the Grant City area; the primary station's record is used for consistency. 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 2928594). Match rule for Grant City: 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 Grant 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.
