The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 9, short of 90°F on every date, while 123 dates carry a normal low at or below freezing, the coldest 19°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 22, then returns to freezing around November 21, covering 123 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 9, when 48% of years recorded at least a hundredth of an inch. The driest is November 12 at 33%. Summed across the calendar, that is about 139 wet dates a year.
The widest day
September 16 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Lima Allen County Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Lima Allen County earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Lima Allen County spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Lima Allen County has no dry season to plan around, though it does carry a wide 46.3°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 4.0" and February 1.9". The three wettest months together take 32% 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.
How Lima Allen County's precipitation splits across the calendar
About 139 days a year record measurable precipitation here, carrying 35.8" between them, or roughly 0.26 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Lima Allen County's climate pattern fits together
heating led · moderate · mid swing
Lima Allen County's energy balance leans toward cold weather: 5,769 annual heating degree days against 847 for cooling. Its 46.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Lima Allen County'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 Lima Allen County's middle-range seasonal profile. The measured spread is 46.3°F. The annual average is 51°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Lima Allen County's 35.8 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Lima Allen County'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 Lima Allen County, 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 Lima Allen County's primary station: LIMA ALLEN CO AP (USW00004850). 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 Lima Allen County; 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 Lima Allen County comes from its primary NOAA station record.
