Weather in September

September, the first month of the autumn in West Selmont, is still a hot month, with an average temperature varying between 87.6°F (30.9°C) and 67.1°F (19.5°C).

Temperature

September observes an average high-temperature of a still tropical 87.6°F (30.9°C), marking an insignificant difference from August's 91.8°F (33.2°C). During September, West Selmont experiences an average low-temperature of 67.1°F (19.5°C) at night.

Heat index

For September, the heat index is computed to be a torrid 100.4°F (38°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
