The year, day by day
The calendar barely moves in Mcclellanville: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 39°F near January 21 and 89°F near July 10.
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 39°F around January 21.
Where the wet dates fall
The likeliest wet date is August 4, when 49% of years recorded at least a hundredth of an inch. The driest is April 24 at 29%. Summed across the calendar, that is about 134 wet dates a year.
The widest day
November 13 carries the biggest normal gap between afternoon and dawn, 19°F between the normal high and the normal low.

Mcclellanville runs a summer-peaked wet season
37% of Mcclellanville's yearly precipitation falls in June, July and August alone, against the 25% an evenly spread year would give those three months. The wettest month is August at 8.3", on a 32.1°F seasonal spread. Warm-season convection and, across the Southwest, the North American monsoon produce this shape: rain arrives in short heavy bursts during the hottest part of the year rather than as long cool-season soaking.
- Wettest three months: August, July, September, taking 40% of the annual total between them.
- Driest month: November at 2.8".
- Winter share: 19% falls in December, January and February.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. A summer-peaked label means the June-August share reaches 35%; it describes timing across an average year, not any single season, and says nothing about how heavy an individual storm can be.
When it rains in Mcclellanville, it arrives in quantity
55.6" of precipitation falls across only about 134 wet days here, averaging 0.41 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 134 a year, 37% of all days
- Average depth per wet day
- 0.41 inches
- Most wet days
- August, about 15

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 Mcclellanville's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Mcclellanville averages 55.6 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 Mcclellanville's middle-range seasonal profile. The measured spread is 32.1°F. The annual average is 65°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Mcclellanville's normal, at 2,029 and 2,098 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 276 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 Mcclellanville'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 Mcclellanville, the bands are descriptive ranges rather than an official NOAA classification or a forecast.
