The year, day by day
Ash Grove works both ends of the calendar. Normal highs climb to 92°F by July 30 and hold at or above 90°F on 41 dates, then normal lows drop to freezing or below on 97 dates, bottoming at 23°F around January 14.
When the heat sits
Normal highs reach 90°F from July 10 through August 19, covering 41 dates. The broader mild season, normal highs of 70°F or more, runs April 21 to October 17.
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 5, then returns to freezing around November 30, covering 97 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 16, when 34% of years recorded at least a hundredth of an inch. The driest is January 6 at 17%. Summed across the calendar, that is about 87 wet dates a year.
The widest day
October 11 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Ash Grove spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 16%, with neither reaching the 35% that would mark a distinct wet season. Ash Grove has no dry season to plan around, though it does carry a wide 45.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: May averages 5.6" and January 2.1". The three wettest months together take 34% 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 Ash Grove, it arrives in quantity
43.5" of precipitation falls across only about 87 wet days here, averaging 0.50 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 87 a year, 24% of all days
- Average depth per wet day
- 0.50 inches
- Most wet days
- May, about 11
- Fewest wet days
- January, about 5
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 Ash Grove, but rarely amounts to much
The normals record 9.3 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 4 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 Ash Grove's climate pattern fits together
heating led · moderate · mid swing
Ash Grove's energy balance leans toward cold weather: 4,345 annual heating degree days against 1,556 for cooling. Its 45.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Ash Grove's frost-free season lasts about 196 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 Ash Grove's middle-range seasonal profile. The measured spread is 45.5°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Ash Grove's 43.5 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Annual snowfall totals 9.3 inches. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Ash Grove'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 Ash Grove, not an official NOAA class or a year-ahead forecast.
