The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 7, short of 90°F on every date, while 147 dates carry a normal low at or below freezing, the coldest 15°F near January 23.
The freezing stretch
The normal low stays at or below 32°F into April 6, then returns to freezing around November 12, covering 147 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 January 8, when 48% of years recorded at least a hundredth of an inch. The driest is August 12 at 29%. Summed across the calendar, that is about 133 wet dates a year.
The widest day
September 18 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Dowagiac spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 20%, with neither reaching the 35% that would mark a distinct wet season. Dowagiac has no dry season to plan around, though it does carry a wide 47.1°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 4.3" and February 2.4". The three wettest months together take 31% 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 Dowagiac's precipitation splits across the calendar
About 133 days a year record measurable precipitation here, carrying 41.7" between them, or roughly 0.31 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 Dowagiac's climate pattern fits together
heating led · moderate · mid swing
Dowagiac's energy balance leans toward cold weather: 6,729 annual heating degree days against 583 for cooling. Its 47.1°F seasonal range still makes the monthly rows more useful than the annual average alone.
Dowagiac's frost-free season lasts about 160 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 Dowagiac's middle-range seasonal profile. The measured spread is 47.1°F. The annual average is 48°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Dowagiac's 41.7 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 Dowagiac'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 Dowagiac, not an official NOAA class or a year-ahead forecast.
