The year, day by day
Graniteville works both ends of the calendar. Normal highs climb to 93°F by July 19 and hold at or above 90°F on 64 dates, then normal lows drop to freezing or below on 70 dates, bottoming at 30°F around January 8.
When the heat sits
Normal highs reach 90°F from June 21 through August 23, covering 64 dates. The broader mild season, normal highs of 70°F or more, runs March 23 to November 4.
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 11, then returns to freezing around December 4, covering 70 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
March 31 carries the biggest normal gap between afternoon and dawn, 33°F between the normal high and the normal low.

Where Graniteville Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 64 days a year, more than four out of five ranked stations record.
Daily temperature swings run wider than most of the country, peaking near 33°F between the normal high and low.
Graniteville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Data-derived climate profile
How Graniteville's climate pattern fits together
mixed demand · mid swing
July and January mark the typical warm and cold ends of the calendar in Graniteville's middle-range seasonal profile. The measured spread is 36.9°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Graniteville's normal, at 2,961 and 1,811 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 206-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
A moisture-range label is withheld because Graniteville'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 Graniteville's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Graniteville, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Graniteville's primary station: GRANITEVILLE 1.2 NE (USC00383665). 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 a census-designated place (GEOID 4530265), not an incorporated municipality. Match rule for Graniteville: 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 Graniteville comes from its primary NOAA station record.
