The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 8, short of 90°F on every date, while 117 dates carry a normal low at or below freezing, the coldest 21°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into March 13, then returns to freezing around November 18, covering 117 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.
Where the wet dates fall
The likeliest wet date is May 3, when 37% of years recorded at least a hundredth of an inch. The driest is January 19 at 18%. Summed across the calendar, that is about 90 wet dates a year.
The widest day
October 2 carries the biggest normal gap between afternoon and dawn, 27°F between the normal high and the normal low.

Perryville Wtp spreads its precipitation across the year
Neither half of the year dominates here: June through August take 25% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Perryville Wtp has no dry season to plan around, though it does carry a wide 46°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.7" and January 2.7". The three wettest months together take 34% 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.
When it rains in Perryville Wtp, it arrives in quantity
46.2" of precipitation falls across only about 90 wet days here, averaging 0.51 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.
- Days with measurable precipitation
- about 90 a year, 25% of all days
- Average depth per wet day
- 0.51 inches
- Most wet days
- May, about 11
- Fewest wet days
- January, about 6
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, and a per-day average is not a forecast of any individual storm.
Snow reaches Perryville Wtp, but rarely amounts to much
The normals record 4.7 inches of snow a year here, most likely in February. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 2 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Perryville Wtp's climate pattern fits together
heating led · wet · mid swing
Perryville Wtp's energy balance leans toward cold weather: 4,878 annual heating degree days against 1,274 for cooling. Its 46.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Perryville Wtp's frost-free season lasts about 184 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 Perryville Wtp's middle-range seasonal profile. The measured spread is 46.0°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Perryville Wtp carries 46.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 4.7 inches. 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 Perryville Wtp'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 Perryville Wtp, 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 Perryville Wtp's primary station: PERRYVILLE WTP (USC00236641). 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 Perryville Wtp; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
