The year, day by day
Summer here tops out rather than builds: the warmest normal high is 87°F around July 15, short of 90°F on every date, while 124 dates carry a normal low at or below freezing, the coldest 21°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into March 16, then returns to freezing around November 14, covering 124 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 15, when 48% of years recorded at least a hundredth of an inch. The driest is November 8 at 33%. Summed across the calendar, that is about 143 wet dates a year.
The widest day
September 25 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Hamilton Butler County Rgnl spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 21%, with neither reaching the 35% that would mark a distinct wet season. Hamilton Butler County Rgnl 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: April averages 4.6" and February 2.4". 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 Hamilton Butler County Rgnl's precipitation splits across the calendar
About 143 days a year record measurable precipitation here, carrying 41.4" between them, or roughly 0.29 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 Hamilton Butler County Rgnl's climate pattern fits together
heating led · moderate · mid swing
Hamilton Butler County Rgnl's energy balance leans toward cold weather: 5,111 annual heating degree days against 1,067 for cooling. Its 44.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Hamilton Butler County Rgnl's frost-free season lasts about 179 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 Hamilton Butler County Rgnl's middle-range seasonal profile. The measured spread is 44.8°F. The annual average is 54°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Hamilton Butler County Rgnl's 41.4 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 Hamilton Butler County Rgnl'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 Hamilton Butler County Rgnl, 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 Hamilton Butler County Rgnl's primary station: HAMILTON BUTLER CO RGNL AP (USW00053855). 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 Hamilton Butler County Rgnl; 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 Hamilton Butler County Rgnl comes from its primary NOAA station record.
