The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 24, short of 90°F on every date, while 179 dates carry a normal low at or below freezing, the coldest 8°F near January 29.
The freezing stretch
The normal low stays at or below 32°F into April 24, then returns to freezing around October 29, covering 179 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
May 22 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Atlanta Stands Nationally
Freezing is routine here by normals standards — the normal low reaches 32°F or colder on about 179 nights a year, more than most ranked stations.
Atlanta earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Atlanta spreads its precipitation across the year
Neither half of the year dominates here: June through August take 31% of the annual total and December through February 17%, with neither reaching the 35% that would mark a distinct wet season. Atlanta has no dry season to plan around, though it does carry a wide 49.5°F gap between its warmest and coldest month.
The gap between the wettest and driest month still matters: October averages 3.5" and February 1.5". The three wettest months together take 31% 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.

Data-derived climate profile
How Atlanta's climate pattern fits together
heating led · moderate · mid swing
Atlanta's energy balance leans toward cold weather: 8,158 annual heating degree days against 332 for cooling. Its 49.5°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 128 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and January mark the typical warm and cold ends of the calendar in Atlanta's middle-range seasonal profile. The measured spread is 49.5°F. The annual average is 43°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Atlanta's 32.0 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Atlanta's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Atlanta, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Atlanta's primary station: ATLANTA (USC00200342). 2 NOAA stations are mapped to the Atlanta area; the primary station's record is used for consistency. For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 2603920), not an incorporated municipality. Match rule for Atlanta: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Atlanta comes from its primary NOAA station record.
