Weather in September
Temperature
September ushers in a minor alteration in Etoile's climate, with the average high-temperature moving from August's sweltering 95.7°F (35.4°C) to a tropical 89.4°F (31.9°C). Etoile experiences an average temperature drop to a pleasant 68.4°F (20.2°C) during September nights.Heat index
The heat index in September is computed to be a blistering 105.8°F (41°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.The metrics for the heat index are tailored for both shady environments and light winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Boost your sun resistance with garments that are densely woven yet spacious. Be watchful! The reflection of snow can enhance the intensity of the Sun's UV radiation nearly double.
