Weather in September
Temperature
The onset of September entails a subtle temperature shift, as the average high-temperature eases from a tropical 87.4°F (30.8°C) in August to a moderately hot 82°F (27.8°C). Rossville observes an average low-temperature of 61°F (16.1°C) during September nights.Heat index
The average heat index in September is evaluated at a tropical 87.8°F (31°C). If one endures exposure and continues to be active, it might result in tiredness and heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a composite of temperature and humidity figures to convey how warm it feels. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
