Weather in September
Temperature
September heralds a minor drop in average high-temperature, sliding from August's tropical 88.3°F (31.3°C) to a warm 81.1°F (27.3°C). Throughout the month of September, Atlanta witnesses an average temperature of 61.9°F (16.6°C).Heat index
For most parts of September, the heat index is computed to be 84.2°F (29°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
