The year, day by day
The year in Hattiesburg Chain Muni runs from a mild 38°F around January 15 to 92°F at the peak near August 2, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 16 through September 5, covering 82 dates. The broader mild season, normal highs of 70°F or more, runs March 10 to November 12.
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 38°F around January 15.
Where the wet dates fall
The likeliest wet date is July 16, when 44% of years recorded at least a hundredth of an inch. The driest is October 17 at 23%. Summed across the calendar, that is about 118 wet dates a year.
The widest day
November 1 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Hattiesburg Chain Muni Stands Nationally
This is one of the wettest normals climates ranked: about 59 inches of precipitation in a normal year, a total fewer than one station in ten surpasses.
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 82 days a year, more than four out of five ranked stations record.
Hattiesburg Chain Muni earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Hattiesburg Chain Muni spreads its precipitation across the year
Neither half of the year dominates here: June through August take 28% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Hattiesburg Chain Muni has no dry season to plan around, though it does carry a 32.8°F seasonal spread.
The gap between the wettest and driest month still matters: June averages 5.8" and November 3.7". 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 Hattiesburg Chain Muni, it arrives in quantity
58.9" of precipitation falls across only about 118 wet days here, averaging 0.50 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 118 a year, 32% of all days
- Average depth per wet day
- 0.50 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 Hattiesburg Chain Muni's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Hattiesburg Chain Muni averages 58.9 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 Hattiesburg Chain Muni's middle-range seasonal profile. The measured spread is 32.8°F. The annual average is 67°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Hattiesburg Chain Muni's normal, at 1,920 and 2,479 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 252 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 Hattiesburg Chain Muni'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 Hattiesburg Chain Muni, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

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 Hattiesburg Chain Muni; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
