The year, day by day
Summer here tops out rather than builds: the warmest normal high is 83°F around July 24, short of 90°F on every date, while 136 dates carry a normal low at or below freezing, the coldest 28°F near February 12.
The freezing stretch
The normal low stays at or below 32°F into April 8, then returns to freezing around November 25, covering 136 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 17 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Data-derived climate profile
How Bowman Dam's climate pattern fits together
heating led · mid swing
Bowman Dam's energy balance leans toward cold weather: 5,655 annual heating degree days against 343 for cooling. Its 31.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Bowman Dam's frost-free season lasts about 170 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and December mark the typical warm and cold ends of the calendar in Bowman Dam's middle-range seasonal profile. The measured spread is 31.2°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 Bowman Dam'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 Bowman Dam'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 Bowman Dam, 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 Bowman Dam's primary station: BOWMAN DAM (USC00041018). 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 Bowman Dam; 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 Bowman Dam 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.
