The year, day by day
The calendar barely moves in Clemson Oconee County: no date carries a normal high of 90°F or a normal low at freezing. The year runs between 33°F near January 15 and 89°F near July 16.
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 33°F around January 15.
Where the wet dates fall
The likeliest wet date is August 2, when 42% of years recorded at least a hundredth of an inch. The driest is September 17 at 29%. Summed across the calendar, that is about 127 wet dates a year.
The widest day
April 5 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Clemson Oconee County 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 Oconee County has no dry season to plan around, though it does carry a 36.6°F seasonal spread.
The gap between the wettest and driest month still matters: August averages 4.9" and May 3.5". 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 Oconee County, it arrives in quantity
49.0" of precipitation falls across only about 127 wet days here, averaging 0.39 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 127 a year, 35% of all days
- Average depth per wet day
- 0.39 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 Clemson Oconee County's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Clemson Oconee County averages 49.0 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 Clemson Oconee County's middle-range seasonal profile. The measured spread is 36.6°F. The annual average is 61°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Clemson Oconee County's normal, at 2,960 and 1,666 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 235-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 Oconee County'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 Oconee County, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Clemson Oconee County's primary station: CLEMSON OCONEE CO AP (USW00053850). For informational purposes only.
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 Oconee County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
