Weather in September
Temperature
The introduction of September notes a subtle temperature variation to a still tropical 87.6°F (30.9°C) from August's 91.2°F (32.9°C). September witnesses an average nighttime temperature of 68.2°F (20.1°C) in Epps, Mississippi.Heat index
Throughout September, the heat index is estimated at a fiery hot 102.2°F (39°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.Be aware that heat index ratings are designed for shaded locations and minor 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 'real feel', comes about by integrating the temperature readings with the humidity levels. 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. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
