The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around August 11, short of 90°F on every date, while 139 dates carry a normal low at or below freezing, the coldest 19°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into March 29, then returns to freezing around November 12, covering 139 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 13 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Data-derived climate profile
How Caldwell's climate pattern fits together
heating led · mid swing
Caldwell's energy balance leans toward cold weather: 5,527 annual heating degree days against 657 for cooling. Its 42.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Caldwell's frost-free season lasts about 167 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 Caldwell's middle-range seasonal profile. The measured spread is 42.8°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Caldwell'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 Caldwell'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 Caldwell, 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 Caldwell's primary station: CALDWELL 3SE (USC00331175). 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 3910940). Match rule for Caldwell: 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 Caldwell 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.
