Weather Averages in Atlanta

Under the Köppen classification, Atlanta has a humid subtropical climate (abbreviated, that’s Cfa). Seasons are distinct, as in, snow in winter, falling leaves in the fall, warm spring, and sweltering summers. Precipitation is generous all year round, allowing plant life to survive and prosper, all this is typical for the inland southern United States.

Summers in Atlanta tend to be hot and humid, with a dampener on temperatures in the form of the city’s elevation. The highest temperatures in the city tend to be in the months of June to September, with averages reaching nearly 90 degrees Fahrenheit in terms of high temperature (this temperature usually occur every 44 days per year on average) and always above 65 degrees in terms of low temperatures. Record high temperatures in those months were all in the 100s range, again, all in Fahrenheit (although one hundred and above temperature readings are uncommon in most years), while lows tend to be split into two types, the type July and August fall into makes their lowest temperature still in the 60s range, and the type of June and September which have their lowest temperatures in the 50s range.

Winters in the city are cool, with occasional snow, I said occasional due to the variable winter weather, though there is an average of freezing days, which is 48 days per year. The lowest temperatures in the whole year (or those that have temperatures that average near freezing to be clear) tend to be in December to February. In December to February, average temperatures in the lows tend to be around or below 3 degrees Fahrenheit, while average lowest temperatures are always slightly below freezing. Record lowest temperatures have reached below nine degrees Fahrenheit (this happened in the Great Blizzard of 1899, which hit Atlanta full blast on February 13). Meanwhile, in the highest recorded temperatures category in Atlanta, the temperature never rose beyond 80 degrees Fahrenheit (in February as well).

March to May and October to November, in a sense, can be labeled as the spring and fall months of Atlanta, as high and low average temperatures in those months tend to be in between the wintery temperatures of December-February and the summery temperatures of June-September.

As for temperature averages (in between hot and cold averages) for the whole year, here they are:

Note: All temperatures in parentheses are in Celsius. Conversely, those not in parentheses are in Fahrenheit.

January: Average temperature of 43.3 (6.3) degrees

February: Average temperature of 47.2 (8.4) degrees

March: Average temperature of 54.3 (12.4) degrees

April: Average temperature of 62.0 (16.7) degrees

May: Average temperature of 70.1 (21.2) degrees

June: Average temperature of 77.3 (25.2) degrees

July: Average temperature of 80.2 (26.8) degrees

August: Average temperature of 79.4 (26.3) degrees

September: Average temperature of 73.5 (23.1) degrees

October: Average temperature of 63.3 (17.4) degrees

November: Average temperature of 54.0 (12.2) degrees

December: Average temperature of 45.3 (7.4) degrees

All these temperature averages combine makes a yearly average temperature of about 62.6 (17) degrees.
