Weather in September

The first month of the autumn, September, is also a hot month in Garden Park, Louisiana, with an average temperature ranging between min 67.8°F (19.9°C) and max 87.8°F (31°C).

Heat index

In September, the heat index is computed to be a torrid 100.4°F (38°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important 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.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
