The year, day by day
The year in Anderson County runs from a mild 33°F around January 14 to 91°F at the peak near July 13, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 4 through August 2, covering 30 dates. The broader mild season, normal highs of 70°F or more, runs April 3 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.
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 14.
Where the wet dates fall
The likeliest wet date is June 13, when 36% of years recorded at least a hundredth of an inch. The driest is October 2 at 24%. Summed across the calendar, that is about 115 wet dates a year.
The widest day
April 9 carries the biggest normal gap between afternoon and dawn, 24°F between the normal high and the normal low.

Anderson 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. Anderson County has no dry season to plan around, though it does carry a 37.3°F seasonal spread.
The gap between the wettest and driest month still matters: December averages 4.4" and October 3.1". The three wettest months together take 28% 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 Anderson County, it arrives in quantity
46.3" of precipitation falls across only about 115 wet days here, averaging 0.40 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 115 a year, 31% of all days
- Average depth per wet day
- 0.40 inches
- Most wet days

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 Anderson County's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Anderson County averages 46.3 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 Anderson County's middle-range seasonal profile. The measured spread is 37.3°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 Anderson County's normal, at 2,911 and 1,807 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 224-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 Anderson 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 Anderson County, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Anderson County's primary station: ANDERSON CO AP (USW00093846). 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 Anderson County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Anderson County comes from its primary NOAA station record.
