The year, day by day
The year in Des Arc runs from a mild 32°F around January 12 to 93°F at the peak near July 26, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 21 through August 26, covering 67 dates. The broader mild season, normal highs of 70°F or more, runs April 7 to October 27.
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.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 32°F around January 12.
Where the wet dates fall
The likeliest wet date is April 30, when 33% of years recorded at least a hundredth of an inch. The driest is September 27 at 19%. Summed across the calendar, that is about 97 wet dates a year.
The widest day
October 16 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Des Arc Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 67 days a year, more than four out of five ranked stations record.
The normal water year runs well above the national norm at roughly 50 inches.

Des Arc spreads its precipitation across the year
Neither half of the year dominates here: June through August take 18% of the annual total and December through February 26%, with neither reaching the 35% that would mark a distinct wet season. Des Arc has no dry season to plan around, though it does carry a 41.9°F seasonal spread.
The gap between the wettest and driest month still matters: April averages 5.5" and August 2.9". The three wettest months together take 32% 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 Des Arc, it arrives in quantity
50.0" of precipitation falls across only about 97 wet days here, averaging 0.52 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 97 a year, 27% of all days
- Average depth per wet day
- 0.52 inches
- Most wet days
- May, about 10
- Fewest wet days
- September, about 6
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 Des Arc, but rarely amounts to much
The normals record 2.3 inches of snow a year here, most likely in February. 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 1 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 Des Arc's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Des Arc averages 50.0 inches of precipitation a year. Annual snowfall totals 2.3 inches. The monthly table supplies the seasonal distribution hidden by that annual total.
July and January mark the typical warm and cold ends of the calendar in Des Arc's middle-range seasonal profile. The measured spread is 41.9°F. The annual average is 63°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Des Arc's normal, at 3,037 and 2,232 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
The frost-free window extends for about 248 days. That is a long calendar measure, but it is not a forecast and does not combine heat, rainfall, soil, or local elevation into a planting recommendation.
These labels group NOAA 1991-2020 normals from Des Arc's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Des Arc, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
