The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 13, short of 90°F on every date, while 92 dates carry a normal low at or below freezing, the coldest 24°F near January 15.
The freezing stretch
The normal low stays at or below 32°F into February 29, then returns to freezing around November 30, covering 92 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
October 15 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Wappapello Dam Stands Nationally
The normal water year runs well above the national norm at roughly 51 inches.
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Wappapello Dam earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.
Monthly Precipitation
Average monthly rainfall
Wappapello Dam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Wappapello Dam has no dry season to plan around, though it does carry a wide 45.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.6" and February 3.5". The three wettest months together take 31% 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 Wappapello Dam's climate pattern fits together
heating led · wet · mid swing
Wappapello Dam's energy balance leans toward cold weather: 4,393 annual heating degree days against 1,441 for cooling. Its 45.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Wappapello Dam's frost-free season lasts about 214 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 Wappapello Dam's middle-range seasonal profile. The measured spread is 45.1°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Wappapello Dam carries 51.4 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 Wappapello 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 Wappapello 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 Wappapello Dam's primary station: WAPPAPELLO DAM (USC00238700). 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 Wappapello 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 Wappapello Dam comes from its primary NOAA station record.
