The year, day by day
The year in Jennings runs from a mild 41°F around January 11 to 91°F at the peak near August 5, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 13 through September 1, covering 51 dates. The broader mild season, normal highs of 70°F or more, runs March 13 to November 15.
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 41°F around January 11.
Where the wet dates fall
The likeliest wet date is July 10, when 45% of years recorded at least a hundredth of an inch. The driest is May 2 at 25%. Summed across the calendar, that is about 124 wet dates a year.
The widest day
October 23 carries the biggest normal gap between afternoon and dawn, 22°F between the normal high and the normal low.

Where Jennings Stands Nationally
This is one of the wettest normals climates ranked: about 64 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Days and nights track unusually close together; the widest normal swing, about 22°F, is narrower than most stations record.
Jennings earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Jennings spreads its precipitation across the year
Neither half of the year dominates here: June through August take 30% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Jennings has no dry season to plan around, though it does carry a 31.2°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 6.8" and March 3.8". 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 Jennings, it arrives in quantity
63.5" of precipitation falls across only about 123 wet days here, averaging 0.51 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 123 a year, 34% of all days
- Average depth per wet day
- 0.51 inches
- Most wet days
- July, about 14
- Fewest wet days
- April, about 8
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 Jennings, but rarely amounts to much
The normals record 0.1 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 0 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 Jennings's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Jennings averages 63.5 inches of precipitation a year. Recorded annual snowfall is negligible. The monthly table supplies the seasonal distribution hidden by that annual total.
August and January mark the typical warm and cold ends of the calendar in Jennings's middle-range seasonal profile. The measured spread is 31.2°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 Jennings's normal, at 1,618 and 2,667 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 288 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 Jennings'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 Jennings, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
