Weather in September
Temperature
A subtle change in temperatures is noted as August gives way to September, with average highs reducing from a torrid 95.4°F (35.2°C) to a tropical 88.7°F (31.5°C). Tennessee Colony's average low-temperature in the month of September is recorded at a pleasant 68.4°F (20.2°C).Heat index
In September, the average heat index is appraised at a very hot 102.2°F (39°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

In Tennessee Colony, the average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high threat to health from unsafe exposure to UV radiation for average individuals.Note: In September, the UV index of 6 transforms into the following advice:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun. Forewarned is forearmed! The Sun's UV radiation can be almost doubled in intensity by snow reflection.
