The year, day by day
Circleville works both ends of the calendar. Normal highs climb to 91°F by July 13 and hold at or above 90°F on 24 dates, then normal lows drop to freezing or below on 182 dates, bottoming at 15°F around January 1.
When the heat sits
Normal highs reach 90°F from July 5 through July 28, covering 24 dates. The broader mild season, normal highs of 70°F or more, runs May 6 to October 10.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into April 16, then returns to freezing around October 18, covering 182 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 August 15, when 26% of years recorded at least a hundredth of an inch. The driest is December 9 at 10%. Summed across the calendar, that is about 63 wet dates a year.
The widest day
June 12 carries the biggest normal gap between afternoon and dawn, 39°F between the normal high and the normal low.

Where Circleville Stands Nationally
Aridity defines the water calendar: about 9 inches in a normal year lands this among the driest tenth of ranked stations.
Day-to-night contrast is extreme by national standards — the widest normal daily swing reaches about 39°F, sharper than nine in ten ranked stations see.
Circleville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Circleville 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 20%, with neither reaching the 35% that would mark a distinct wet season. Circleville has no dry season to plan around, though it does carry a 42.8°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 1.5" and December 0.5". The three wettest months together take 39% 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.
Circleville is dry, and what does fall arrives gently
Only about 62 days a year record measurable precipitation here, 17% of the calendar, and they carry 9.2" between them. At roughly 0.15 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.
The wettest month by count is August at about 8 wet days; the driest is December at about 3.
A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.
Winter brings real snow to Circleville
Circleville averages 19.4 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 10 days that record measurable snow. That is depth accumulating on the ground, which is why it can exceed the annual precipitation figure: precipitation counts the liquid the snow melts down to, and fresh snow is mostly air.
- Annual snowfall: 19.4 inches of depth.
- Days recording measurable snow: about 10 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 21% of the year's precipitation.
NOAA 1991-2020 normals. The ten-to-one ratio is a convention, not a measurement: real ratios vary with temperature, so treat the share as an order of magnitude rather than an exact split.

Snow and freeze rhythm
When cold and snow define Circleville
heating led · dry · mid swing
Circleville's energy balance leans toward cold weather: 5,964 annual heating degree days against 538 for cooling. Its 42.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 127 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
