Weather in September
Temperature
During the shift to September, a minor reduction in average high-temperature is observed, shifting from a fiery hot 96.8°F (36°C) in August to a hot 89.8°F (32.1°C). Pettus experiences a steady low-temperature of 73°F (22.8°C) throughout September.Heat index
The heat index value during September is calculated to be a blisteringly hot 105.8°F (41°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are largely significant for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
