Weather in September

The first month of the autumn, September, is still a tropical month in Rougon, Louisiana, with an average temperature fluctuating between 87.8°F (31°C) and 69.1°F (20.6°C).

Temperature

Rougon signifies an average high-temperature of a still tropical 87.8°F (31°C) in September, closely mirroring the 91.6°F (33.1°C) of August. The average low-temperature, in September, is an agreeable 69.1°F (20.6°C).

Heat index

For most parts of September, the heat index is appraised at a scorching 105.8°F (41°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat. Remember this! The UV radiation of the Sun can be nearly doubled by the reflective properties of snow.
