The year, day by day
Summer here tops out rather than builds: the warmest normal high is 89°F around July 15, short of 90°F on every date, while 121 dates carry a normal low at or below freezing, the coldest 20°F near January 24.
The freezing stretch
The normal low stays at or below 32°F into March 18, then returns to freezing around November 19, covering 121 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 16 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Data-derived climate profile
How Glenn Dale Bell Stn's climate pattern fits together
heating led · mid swing
Glenn Dale Bell Stn's energy balance leans toward cold weather: 4,846 annual heating degree days against 1,202 for cooling. Its 44.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Glenn Dale Bell Stn's frost-free season lasts about 183 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 Glenn Dale Bell Stn's middle-range seasonal profile. The measured spread is 44.6°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Glenn Dale Bell Stn'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 Glenn Dale Bell Stn'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 Glenn Dale Bell Stn, 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 Glenn Dale Bell Stn's primary station: GLENN DALE BELL STN (USC00183675). 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 Glenn Dale Bell Stn; 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 Glenn Dale Bell Stn 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.
