Weather in September
Temperature
Upon the beginning of September, Vacherie's high-temperatures register at a still tropical 86.9°F (30.5°C), closely mirroring the preceding month. Vacherie, in September, observes a steady average low-temperature of 72°F (22.2°C).Heat index
Throughout September, the heat index is estimated at a very hot 102.2°F (39°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
