The year, day by day
Summer here tops out rather than builds: the warmest normal high is 84°F around July 12, short of 90°F on every date, while 124 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 22, then returns to freezing around November 20, covering 124 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 9, when 40% of years recorded at least a hundredth of an inch. The driest is January 26 at 21%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
May 15 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Chicago Palwaukee spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 13%, with neither reaching the 35% that would mark a distinct wet season. Chicago Palwaukee has no dry season to plan around, though it does carry a wide 49.8°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: June averages 4.0" and February 1.3". 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.
How Chicago Palwaukee's precipitation splits across the calendar
About 112 days a year record measurable precipitation here, carrying 32.3" between them, or roughly 0.29 inches on a typical wet day. That sits in the middle band: neither the many-light-days pattern of the Pacific Northwest and the Great Lakes, nor the few-heavy-events pattern of the Gulf and the desert Southwest.
A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year and say nothing about the heaviest single storm on record.

Data-derived climate profile
How Chicago Palwaukee's climate pattern fits together
heating led · moderate · mid swing
Chicago Palwaukee's energy balance leans toward cold weather: 6,085 annual heating degree days against 933 for cooling. Its 49.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Chicago Palwaukee'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 Chicago Palwaukee's middle-range seasonal profile. The measured spread is 49.8°F. The annual average is 51°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Chicago Palwaukee's 32.3 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 Chicago Palwaukee'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 Chicago Palwaukee, 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 Chicago Palwaukee's primary station: CHICAGO PALWAUKEE AP (USW00004838). 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 Chicago Palwaukee; 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 Chicago Palwaukee comes from its primary NOAA station record.
