The year, day by day
Parma Exp Stn works both ends of the calendar. Normal highs climb to 95°F by July 28 and hold at or above 90°F on 46 dates, then normal lows drop to freezing or below on 144 dates, bottoming at 22°F around January 1.
When the heat sits
Normal highs reach 90°F from July 7 through August 21, covering 46 dates. The broader mild season, normal highs of 70°F or more, runs May 4 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 March 19, then returns to freezing around October 28, covering 144 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 January 11, when 32% of years recorded at least a hundredth of an inch. The driest is July 27 at 7%. Summed across the calendar, that is about 78 wet dates a year.
The widest day
August 4 carries the biggest normal gap between afternoon and dawn, 37°F between the normal high and the normal low.

Where Parma Exp Stn Stands Nationally
Aridity defines the water calendar: about 10 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 37°F, sharper than nine in ten ranked stations see.

Parma Exp Stn spreads its precipitation across the year
Neither half of the year dominates here: June through August take 12% of the annual total and December through February 33%, with neither reaching the 35% that would mark a distinct wet season. Parma Exp Stn has no dry season to plan around, though it does carry a 44.7°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 1.4" and August 0.2". The three wettest months together take 38% 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.
Parma Exp Stn is dry, and what does fall arrives gently
Only about 78 days a year record measurable precipitation here, 21% of the calendar, and they carry 10.0" between them. At roughly 0.13 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 January at about 10 wet days; the driest is August at about 2.
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.
Snow reaches Parma Exp Stn, but rarely amounts to much
The normals record 11.5 inches of snow a year here, most likely in December. 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 9 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.

Scarce-water calendar
Where Parma Exp Stn's limited precipitation lands
heating led · dry · mid swing
Parma Exp Stn's energy balance leans toward cold weather: 5,691 annual heating degree days against 789 for cooling. Its 44.7°F seasonal range still makes the monthly rows more useful than the annual average alone.
Parma Exp Stn's frost-free season lasts about 165 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 Parma Exp Stn's middle-range seasonal profile. The measured spread is 44.7°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Parma Exp Stn's cold-season load does not imply a wet climate. Annual precipitation is 10.0 inches, which places the station in PlainClimate's dry range. Annual snowfall totals 11.5 inches. The snowfall and rainfall fields should be read separately rather than inferred from temperature.

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 Parma Exp Stn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
