The year, day by day
Bentonville works both ends of the calendar. Normal highs climb to 90°F by August 3 and hold at or above 90°F on 23 dates, then normal lows drop to freezing or below on 99 dates, bottoming at 24°F around January 18.
When the heat sits
Normal highs reach 90°F from July 24 through August 15, covering 23 dates. The broader mild season, normal highs of 70°F or more, runs April 17 to October 20.
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 3, then returns to freezing around November 26, covering 99 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 1, when 32% of years recorded at least a hundredth of an inch. The driest is January 19 at 18%. Summed across the calendar, that is about 85 wet dates a year.
The widest day
October 4 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Bentonville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 18%, with neither reaching the 35% that would mark a distinct wet season. Bentonville has no dry season to plan around, though it does carry a 42.8°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 6.3" and February 2.7". 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.
When it rains in Bentonville, it arrives in quantity
47.3" of precipitation falls across only about 85 wet days here, averaging 0.56 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 85 a year, 23% of all days
- Average depth per wet day
- 0.56 inches
- Most wet days
- May, about 10
- Fewest wet days
- February, 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 Bentonville, but rarely amounts to much
The normals record 9.5 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 Bentonville's climate pattern fits together
heating led · wet · mid swing
Bentonville's energy balance leans toward cold weather: 4,186 annual heating degree days against 1,398 for cooling. Its 42.8°F seasonal range still makes the monthly rows more useful than the annual average alone.
Bentonville's frost-free season lasts about 197 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 Bentonville's middle-range seasonal profile. The measured spread is 42.8°F. The annual average is 57°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Bentonville carries 47.3 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 9.5 inches. That distinction matters because a wet annual total can arrive as rain, snow, or a mixture at different times.
These labels group NOAA 1991-2020 normals from Bentonville'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 Bentonville, not an official NOAA class or a year-ahead forecast.
