Weather in September
Temperature
The onset of September in Calhoun is marked by a minor decrease in temperature, transitioning from a tropical 88.9°F (31.6°C) in August to a moderately hot 83.1°F (28.4°C). In September, Calhoun reports a consistent average low-temperature of 62.2°F (16.8°C) during the nights.Heat index
During September, the heat index is evaluated at a tropical 89.6°F (32°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
