The year, day by day
Summer here tops out rather than builds: the warmest normal high is 85°F around July 8, short of 90°F on every date, while 125 dates carry a normal low at or below freezing, the coldest 16°F near January 19.
The freezing stretch
The normal low stays at or below 32°F into March 20, then returns to freezing around November 17, covering 125 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 1, when 32% of years recorded at least a hundredth of an inch. The driest is January 22 at 19%. Summed across the calendar, that is about 86 wet dates a year.
The widest day
September 27 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Rushville 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 15%, with neither reaching the 35% that would mark a distinct wet season. Rushville has no dry season to plan around, though it does carry a wide 49.9°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.3" and January 1.8". The three wettest months together take 35% 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 Rushville, it arrives in quantity
40.9" of precipitation falls across only about 86 wet days here, averaging 0.47 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 86 a year, 24% of all days
- Average depth per wet day
- 0.47 inches
- Most wet days
- May, about 10

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.

Data-derived climate profile
How Rushville's climate pattern fits together
heating led · moderate · mid swing
Rushville's energy balance leans toward cold weather: 5,791 annual heating degree days against 987 for cooling. Its 49.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Rushville's frost-free season lasts about 190 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 Rushville's middle-range seasonal profile. The measured spread is 49.9°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Rushville's 40.9 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 Rushville'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 Rushville, not an official NOAA class or a year-ahead forecast.
