Weather in September
Temperature
In September, the meteorological conditions change slightly, with the average high-temperature moving from a hot 93.9°F (34.4°C) in August to a still tropical 88.3°F (31.3°C). Calhoun reports a consistent average low-temperature of 67.1°F (19.5°C) throughout September nights.Heat index
The heat index value for September is appraised at a very hot 102.2°F (39°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
