The year, day by day
Mullins works both ends of the calendar. Normal highs climb to 90°F by July 11 and hold at or above 90°F on 12 dates, then normal lows drop to freezing or below on 4 dates, bottoming at 32°F around January 19.
When the heat sits
Normal highs reach 90°F from July 9 through July 20, covering 12 dates. The broader mild season, normal highs of 70°F or more, runs April 2 to October 26.
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.
The freezing stretch
Freezing normal lows persist into January 22, covering 4 dates.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
Where the wet dates fall
The likeliest wet date is August 1, when 37% of years recorded at least a hundredth of an inch. The driest is October 24 at 23%. Summed across the calendar, that is about 112 wet dates a year.
The widest day
April 5 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Mullins 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 21%, with neither reaching the 35% that would mark a distinct wet season. Mullins has no dry season to plan around, though it does carry a 37°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 6.2" and April 3.5". The three wettest months together take 33% 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 Mullins, it arrives in quantity
53.2" of precipitation falls across only about 112 wet days here, averaging 0.48 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
- 0.48 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 Mullins's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Mullins averages 53.2 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 Mullins's middle-range seasonal profile. The measured spread is 37.0°F. The annual average is 62°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Mullins's normal, at 2,886 and 1,769 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 230-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 Mullins'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 Mullins, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
