The year, day by day
Summer here tops out rather than builds: the warmest normal high is 80°F around July 18, short of 90°F on every date, while 168 dates carry a normal low at or below freezing, the coldest 8°F near January 18.
The freezing stretch
The normal low stays at or below 32°F into April 14, then returns to freezing around October 30, covering 168 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.
The widest day
September 9 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Slinger Wwtp Stands Nationally
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Slinger Wwtp earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Slinger Wwtp runs a summer-peaked wet season
35% of Slinger Wwtp's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is June at 4.5", on a wide 52.3°F gap between its warmest and coldest month. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: June, July, May, taking 35% of the annual total between them.
- Driest month: February at 1.5".
- Winter share: 14% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.

Data-derived climate profile
How Slinger Wwtp's climate pattern fits together
heating led · moderate · mid swing
Slinger Wwtp's energy balance leans toward cold weather: 7,884 annual heating degree days against 411 for cooling. Its 52.3°F seasonal range still makes the monthly rows more useful than the annual average alone.
Slinger Wwtp's frost-free season lasts about 153 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 Slinger Wwtp's middle-range seasonal profile. The measured spread is 52.3°F. The annual average is 44°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Slinger Wwtp's 35.5 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 Slinger Wwtp'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 Slinger Wwtp, 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 Slinger Wwtp's primary station: SLINGER WWTP (USC00477796). 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 Slinger Wwtp; 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 Slinger Wwtp comes from its primary NOAA station record.
