The year, day by day
The year in Clemson Univ runs from a mild 32°F around January 14 to 91°F at the peak near July 12, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 28 through August 12, covering 46 dates. The broader mild season, normal highs of 70°F or more, runs April 4 to October 28.
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 32°F around January 14.
Where the wet dates fall
The likeliest wet date is December 24, when 37% of years recorded at least a hundredth of an inch. The driest is October 2 at 27%. Summed across the calendar, that is about 120 wet dates a year.
The widest day
November 3 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Clemson Univ spreads its precipitation across the year
Neither half of the year dominates here: June through August take 26% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Clemson Univ has no dry season to plan around, though it does carry a 36.9°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 5.3" and October 3.8". 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 Clemson Univ, it arrives in quantity
52.4" of precipitation falls across only about 120 wet days here, averaging 0.44 inches each. Fewer days carry more water: the year's total is delivered in comparatively heavy events rather than persistent damp.

- about 120 a year, 33% of all days
- Average depth per wet day
- 0.44 inches
- Most wet days
- December, about 11
- Fewest wet days
- October, about 8
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 Clemson Univ, but rarely amounts to much
The normals record 2.2 inches of snow a year here, most likely in January. 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 1 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 Clemson Univ's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Clemson Univ averages 52.4 inches of precipitation a year. Annual snowfall totals 2.2 inches. 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 Clemson Univ's middle-range seasonal profile. The measured spread is 36.9°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 Clemson Univ's normal, at 2,989 and 1,743 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 216-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 Clemson Univ'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 Clemson Univ, 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 Clemson Univ; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
