Weather in September
Temperature
The advent of September signifies a minor shift to an average high-temperature of a still hot 86.9°F (30.5°C), aligning closely with August. During September, Pelahatchie sees a mean low-temperature of 67.1°F (19.5°C).Heat index
The heat index value for September is computed to be a torrid 98.6°F (37°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Heat index determinations are made taking into account the shade and light air movements. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
