Weather in September
Temperature
The transition into September reveals an average high-temperature of a still tropical 86.4°F (30.2°C), mirroring a close resemblance to August. Tuscaloosa, during September nights, observes an average temperature of 66.7°F (19.3°C).Heat index
The heat index value during September is computed to be a sweltering 96.8°F (36°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.One should consider that heat index numbers are for shaded settings and light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
