The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 5, short of 90°F on every date, while 125 dates carry a normal low at or below freezing, the coldest 18°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into March 21, then returns to freezing around November 18, 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 April 25, when 43% of years recorded at least a hundredth of an inch. The driest is September 2 at 25%. Summed across the calendar, that is about 124 wet dates a year.
The widest day
September 24 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Indianapolis SE Side spreads its precipitation across the year
Neither half of the year dominates here: June through August take 29% of the annual total and December through February 19%, with neither reaching the 35% that would mark a distinct wet season. Indianapolis SE Side has no dry season to plan around, though it does carry a wide 47.4°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 5.4" and February 2.3". The three wettest months together take 33% 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 Indianapolis SE Side, it arrives in quantity
44.6" of precipitation falls across only about 123 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 123 a year, 34% of all days
- Average depth per wet day
- 0.36 inches
- Most wet days
- May, about 13

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 Indianapolis SE Side's climate pattern fits together
heating led · moderate · mid swing
Indianapolis SE Side's energy balance leans toward cold weather: 5,704 annual heating degree days against 947 for cooling. Its 47.4°F seasonal range still makes the monthly rows more useful than the annual average alone.
Indianapolis SE Side's frost-free season lasts about 184 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 Indianapolis SE Side's middle-range seasonal profile. The measured spread is 47.4°F. The annual average is 52°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Indianapolis SE Side's 44.6 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 Indianapolis SE Side'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 Indianapolis SE Side, 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 Indianapolis SE Side's primary station: INDIANAPOLIS SE SIDE (USC00124272). 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 Indianapolis SE Side; 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 Indianapolis SE Side comes from its primary NOAA station record.
