The year, day by day
The year in Shreveport Dwtn runs from a mild 39°F around January 5 to 96°F at the peak near August 1, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 5 through September 14, covering 102 dates. The broader mild season, normal highs of 70°F or more, runs March 16 to November 9.
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 39°F around January 5.
Where the wet dates fall
The likeliest wet date is February 21, when 33% of years recorded at least a hundredth of an inch. The driest is August 3 at 21%. Summed across the calendar, that is about 101 wet dates a year.
The widest day
October 18 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Where Shreveport Dwtn Stands Nationally
Summers here run among the most heat-heavy normals calendars in the country: on about 102 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.
Days and nights track unusually close together; the widest normal swing, about 23°F, is narrower than most stations record.
Shreveport Dwtn earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Shreveport Dwtn spreads its precipitation across the year
Neither half of the year dominates here: June through August take 22% of the annual total and December through February 28%, with neither reaching the 35% that would mark a distinct wet season. Shreveport Dwtn has no dry season to plan around, though it does carry a 36.6°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 4.8" and August 2.6". The three wettest months together take 29% 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 Shreveport Dwtn, it arrives in quantity
48.9" of precipitation falls across only about 101 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.

- about 101 a year, 28% of all days
- Average depth per wet day
- 0.49 inches

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.

Data-derived climate profile
How Shreveport Dwtn's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Shreveport Dwtn averages 48.9 inches of precipitation a year. Snowfall is not added to the interpretation because its annual value is missing. 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 Shreveport Dwtn's middle-range seasonal profile. The measured spread is 36.6°F. The annual average is 68°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Shreveport Dwtn's normal, at 1,947 and 2,894 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 269 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 Shreveport Dwtn'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 Shreveport Dwtn, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Shreveport Dwtn's primary station: SHREVEPORT DWTN AP (USW00053905). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Shreveport Dwtn; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
