Weather in September
Temperature
McGehees marks the start of September with an average high-temperature of a still tropical 87.1°F (30.6°C), hinting at a slight fluctuation from August's 90.9°F (32.7°C). September nights are marked by an average temperature drop to a refreshing 67.5°F (19.7°C).Heat index
Throughout September, the heat index is calculated to be a torrid 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
