The year, day by day
The year in Atlanta Fulton County runs from a mild 33°F around January 13 to 90°F at the peak near July 22, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from July 13 through August 8, covering 27 dates. The broader mild season, normal highs of 70°F or more, runs April 1 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 33°F around January 13.
Where the wet dates fall
The likeliest wet date is June 28, when 43% of years recorded at least a hundredth of an inch. The driest is October 20 at 28%. Summed across the calendar, that is about 124 wet dates a year.
The widest day
April 12 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Atlanta Fulton County spreads its precipitation across the year
Neither half of the year dominates here: June through August take 27% of the annual total and December through February 27%, with neither reaching the 35% that would mark a distinct wet season. Atlanta Fulton County has no dry season to plan around, though it does carry a 36.5°F seasonal spread.
The gap between the wettest and driest month still matters: July averages 5.0" and September 3.4". 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 Atlanta Fulton County, it arrives in quantity
48.1" of precipitation falls across only about 123 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.

- about 123 a year, 34% of all days
- Average depth per wet day

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 Atlanta Fulton County's climate pattern fits together
mixed demand · wet · mid swing
Water is prominent even though neither heating nor cooling wholly defines the record. Atlanta Fulton County averages 48.1 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 Atlanta Fulton County's middle-range seasonal profile. The measured spread is 36.5°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 Atlanta Fulton County's normal, at 2,775 and 1,825 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 229-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 Atlanta Fulton 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 Atlanta Fulton 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 Atlanta Fulton County's primary station: ATLANTA FULTON CO AP (USW00003888). 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 Atlanta Fulton County; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
