Weather in September
Temperature
September's arrival signals a moderate reduction in the average high-temperature, easing from a tropical 94.5°F (34.7°C) in August to a still hot 89.1°F (31.7°C). In the month of September, the average temperature in Vanderbilt dips to an agreeable 73°F (22.8°C) during the night.Heat index
The average heat index in September is computed to be a blisteringly hot 105.8°F (41°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', melds the effects of warmth and moisture to generate a feeling of heat. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
