Weather in September
Temperature
Tuscaloosa marks the onset of September with an average high-temperature of a still hot 86.4°F (30.2°C), a subtle shift from August's 91°F (32.8°C). Tuscaloosa experiences a consistent average temperature of 66.7°F (19.3°C) throughout the nights in September.Heat index
The heat index for September is estimated at a sweltering 96.8°F (36°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. 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 largely significant 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.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.
