The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 25, short of 90°F on every date, while 228 dates carry a normal low at or below freezing, the coldest 17°F near December 17.
The freezing stretch
The normal low stays at or below 32°F into May 16, then returns to freezing around October 2, covering 228 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
July 30 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Data-derived climate profile
How Brothers's climate pattern fits together
heating led · mid swing
Brothers's energy balance leans toward cold weather: 8,068 annual heating degree days against 126 for cooling. Its 36.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
A frost-free growing-season length is not available for Brothers. That missing field is kept separate from the observed temperature and precipitation record rather than filled from a regional estimate.
July and December mark the typical warm and cold ends of the calendar in Brothers's middle-range seasonal profile. The measured spread is 36.6°F. The annual average is 43°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Brothers'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 Brothers'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 Brothers, 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 Brothers's primary station: BROTHERS (USC00351067). 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 Brothers; 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 Brothers 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.
