The year, day by day
The calendar barely moves in Natchez: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 36°F near January 17 and 90°F near July 23.
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 36°F around January 17.
Where the wet dates fall
The likeliest wet date is January 7, when 36% of years recorded at least a hundredth of an inch. The driest is October 1 at 20%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
October 28 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Where Natchez Stands Nationally
This is one of the wettest normals climates ranked: about 60 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Natchez earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Natchez spreads its precipitation across the year
Neither half of the year dominates here: June through August take 23% of the annual total and December through February 29%, with neither reaching the 35% that would mark a distinct wet season. Natchez has no dry season to plan around, though it does carry a 34°F seasonal spread.
The gap between the wettest and driest month still matters: January averages 6.2" and October 4.0". The three wettest months together take 30% 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 Natchez, it arrives in quantity
60.1" of precipitation falls across only about 112 wet days here, averaging 0.54 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 112 a year, 31% of all days
- Average depth per wet day
- 0.54 inches
- Most wet days
- January, about 11
- Fewest wet days
- October, 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 Natchez, but rarely amounts to much
The normals record 0.3 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 Natchez's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Natchez averages 60.1 inches of precipitation a year. Recorded annual snowfall is negligible. 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 Natchez's middle-range seasonal profile. The measured spread is 34.0°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Natchez's normal, at 2,361 and 2,106 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.
A roughly 238-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
These labels group NOAA 1991-2020 normals from Natchez'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 Natchez, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
