The year, day by day
Summer here tops out rather than builds: the warmest normal high is 79°F around July 16, short of 90°F on every date, while 157 dates carry a normal low at or below freezing, the coldest 14°F near January 26.
The freezing stretch
The normal low stays at or below 32°F into April 10, then returns to freezing around November 6, covering 157 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 22 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Francis E Walter Dam Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Francis E Walter Dam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Francis E Walter Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Francis E Walter Dam has no dry season to plan around, though it does carry a 44.8°F seasonal spread.
The gap between the wettest and driest month still matters: September averages 5.2" and February 2.6". The three wettest months together take 30% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

Data-derived climate profile
How Francis E Walter Dam's climate pattern fits together
heating led · wet · mid swing
Francis E Walter Dam's energy balance leans toward cold weather: 7,024 annual heating degree days against 345 for cooling. Its 44.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Francis E Walter Dam's frost-free season lasts about 152 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 Francis E Walter Dam's middle-range seasonal profile. The measured spread is 44.8°F. The annual average is 47°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Francis E Walter Dam carries 48.8 inches of precipitation in a normal year, inside PlainClimate's wet range. Snowfall is not added to the interpretation because its annual value is missing. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Francis E Walter 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 Francis E Walter 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 Francis E Walter Dam's primary station: FRANCIS E WALTER DAM (USC00363018). 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 Francis E Walter 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 Francis E Walter Dam comes from its primary NOAA station record.
