The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 25, short of 90°F on every date, while 184 dates carry a normal low at or below freezing, the coldest 3°F near January 17.
The freezing stretch
The normal low stays at or below 32°F into April 20, then returns to freezing around October 20, covering 184 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 3 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Data-derived climate profile
How Granville's climate pattern fits together
heating led · high swing
Winter and seasonal range jointly define this record. Granville logs 8,755 heating degree days, more than twice its 503 cooling total, while the typical coldest-to-warmest-month gap reaches 59.5°F. The annual mean therefore compresses two materially different seasons.
Only about 145 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.
Granville's calendar has a pronounced split: July and January mark the typical warm and cold ends of the calendar, with 59.5°F between them. The annual average is 42°F. That average is context, while the monthly highs, lows, and precipitation totals describe the lived parts of the year.
A moisture-range label is withheld because Granville'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 Granville'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 Granville, 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 Granville's primary station: GRANVILLE (USC00323686). 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 3832660). Match rule for Granville: 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 Granville 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.
