The year, day by day
Osawatomie works both ends of the calendar. Normal highs climb to 90°F by July 26 and hold at or above 90°F on 16 dates, then normal lows drop to freezing or below on 116 dates, bottoming at 18°F around January 14.
When the heat sits
Normal highs reach 90°F from July 22 through August 6, covering 16 dates. The broader mild season, normal highs of 70°F or more, runs May 2 to October 13.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
The freezing stretch
The normal low stays at or below 32°F into March 13, then returns to freezing around November 19, covering 116 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 10, when 30% of years recorded at least a hundredth of an inch. The driest is January 4 at 12%. Summed across the calendar, that is about 71 wet dates a year.
The widest day
October 10 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Osawatomie 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 11%, with neither reaching the 35% that would mark a distinct wet season. Osawatomie has no dry season to plan around, though it does carry a wide 49.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.5" and January 1.1". The three wettest months together take 39% 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 Osawatomie, it arrives in quantity
38.9" of precipitation falls across only about 71 wet days here, averaging 0.55 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 71 a year, 19% of all days
- Average depth per wet day
- 0.55 inches
- Most wet days
- May, about 10
- Fewest wet days
- January, about 4
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.
Snow reaches Osawatomie, but rarely amounts to much
The normals record 8.4 inches of snow a year here, most likely in January. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.
A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 3 days a year record any measurable snow at all.
NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Data-derived climate profile
How Osawatomie's climate pattern fits together
heating led · moderate · mid swing
Osawatomie's energy balance leans toward cold weather: 5,016 annual heating degree days against 1,394 for cooling. Its 49.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Osawatomie's frost-free season lasts about 194 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 Osawatomie's middle-range seasonal profile. The measured spread is 49.5°F. The annual average is 55°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Osawatomie's 38.9 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 8.4 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Osawatomie'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 Osawatomie, not an official NOAA class or a year-ahead forecast.
