The year, day by day
The year in Carville runs from a mild 43°F around January 8 to 91°F at the peak near August 3, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 15 through August 24, covering 41 dates. The broader mild season, normal highs of 70°F or more, runs March 7 to November 16.
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 43°F around January 8.
Where the wet dates fall
The likeliest wet date is July 11, when 38% of years recorded at least a hundredth of an inch. The driest is October 16 at 22%. Summed across the calendar, that is about 107 wet dates a year.
The widest day
November 10 carries the biggest normal gap between afternoon and dawn, 20°F between the normal high and the normal low.

Where Carville Stands Nationally
This is one of the wettest normals climates ranked: about 63 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Among the steadiest day-night climates ranked: even the widest normal daily swing holds to roughly 20°F.
Carville earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Carville spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 24%, with neither reaching the 35% that would mark a distinct wet season. Carville has no dry season to plan around, though it does carry a 30.1°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 7.1" and November 4.1". 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 Carville, it arrives in quantity
62.5" of precipitation falls across only about 107 wet days here, averaging 0.58 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 107 a year, 29% of all days
- Average depth per wet day
- 0.58 inches
- Most wet days
- July, about 12

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 Carville's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Carville averages 62.5 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 Carville's middle-range seasonal profile. The measured spread is 30.1°F. The annual average is 69°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Carville's normal, at 1,402 and 2,767 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 307 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 Carville'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 Carville, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Carville's primary station: CARVILLE 2 SW (USC00161565). 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 Carville; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Carville comes from its primary NOAA station record.
