The year, day by day
Poplar Bluff works both ends of the calendar. Normal highs climb to 91°F by July 11 and hold at or above 90°F on 47 dates, then normal lows drop to freezing or below on 83 dates, bottoming at 26°F around January 13.
When the heat sits
Normal highs reach 90°F from June 29 through August 14, covering 47 dates. The broader mild season, normal highs of 70°F or more, runs April 16 to October 21.
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 February 24, then returns to freezing around December 4, covering 83 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 7, when 38% of years recorded at least a hundredth of an inch. The driest is September 13 at 22%. Summed across the calendar, that is about 106 wet dates a year.
The widest day
October 13 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Poplar Bluff spreads its precipitation across the year
Neither half of the year dominates here: June through August take 24% of the annual total and December through February 22%, with neither reaching the 35% that would mark a distinct wet season. Poplar Bluff has no dry season to plan around, though it does carry a wide 45.6°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: April averages 5.9" and September 3.3". 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.
When it rains in Poplar Bluff, it arrives in quantity
52.2" of precipitation falls across only about 106 wet days here, averaging 0.49 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 106 a year, 29% of all days
- Average depth per wet day
- 0.49 inches
- Most wet days
- May, about 11
- Fewest wet days
- September, about 7
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 Poplar Bluff, but rarely amounts to much
The normals record 5.4 inches of snow a year here, most likely in December. 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 2 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 Poplar Bluff's climate pattern fits together
heating led · wet · mid swing
Poplar Bluff's energy balance leans toward cold weather: 4,027 annual heating degree days against 1,749 for cooling. Its 45.6°F seasonal range still makes the monthly rows more useful than the annual average alone.
Poplar Bluff's frost-free season lasts about 221 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 Poplar Bluff's middle-range seasonal profile. The measured spread is 45.6°F. The annual average is 59°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Alongside its heating load, Poplar Bluff carries 52.2 inches of precipitation in a normal year, inside PlainClimate's wet range. Annual snowfall totals 5.4 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 Poplar Bluff'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 Poplar Bluff, not an official NOAA class or a year-ahead forecast.
