Weather in September

The first month of the autumn, September, is still a tropical month in Loreauville, Louisiana, with an average temperature fluctuating between 86.7°F (30.4°C) and 70.7°F (21.5°C).

Loreauville's shift into September sets the average high-temperature at a still tropical 86.7°F (30.4°C), a figure that deviates only slightly from August's 90.1°F (32.3°C). Loreauville anticipates an average minimum temperature of 70.7°F (21.5°C) in the month of September.

Heat index

For most parts of September, the heat index is computed to be a sweltering 102.2°F (39°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
