Weather in September
Temperature
At the start of September, Nashville's average high-temperature reaches a moderately hot 85.5°F (29.7°C), subtly different from the preceding month. In the month of September, the temperature generally rests at an average low of 69.1°F (20.6°C).Heat index
The heat index for September is calculated to be a sweltering 96.8°F (36°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
