The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 5, short of 90°F on every date, while 139 dates carry a normal low at or below freezing, the coldest 15°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into March 29, then returns to freezing around November 12, covering 139 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 7, when 45% of years recorded at least a hundredth of an inch. The driest is February 5 at 26%. Summed across the calendar, that is about 125 wet dates a year.
The widest day
September 19 carries the biggest normal gap between afternoon and dawn, 29°F between the normal high and the normal low.

Piper City 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 21%, with neither reaching the 35% that would mark a distinct wet season. Piper City has no dry season to plan around, though it does carry a wide 50°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 4.9" and February 2.8". 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.
When it rains in Piper City, it arrives in quantity
44.4" of precipitation falls across only about 124 wet days here, averaging 0.36 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 124 a year, 34% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- May, about 14
- Fewest wet days
- February, about 7
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.
Winter brings real snow to Piper City
Piper City averages 24.7 inches of snowfall a year, with January the snowiest month on the normals, spread across roughly 16 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: 24.7 inches of depth.
- Days recording measurable snow: about 16 a year.
- At a rough ten-to-one melt ratio, snow accounts for on the order of 6% 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.

heating led · moderate · mid swing
Piper City's energy balance leans toward cold weather: 5,770 annual heating degree days against 1,037 for cooling. Its 50.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Piper City's frost-free season lasts about 178 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
