Weather in September
Temperature
Poydras indicates an average high-temperature of a still hot 86.2°F (30.1°C) in September, showing minor variation from August's 89.2°F (31.8°C). During September, Poydras experiences an average low-temperature of 76.6°F (24.8°C) at night.Heat index
In September, the heat index is computed to be a fiery hot 96.8°F (36°C). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. 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. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
