Weather in September
Temperature
Gantt, Alabama, greets September with an average high-temperature of a still hot 87.3°F (30.7°C), marking a slight deviation from the preceding month. During the month of September, the temperature in Gantt falls to an average of 68.7°F (20.4°C).Heat index
In September, the average heat index is computed to be a very hot 100.4°F (38°C). Use additional protective measures, heat cramps and heat exhaustion are possible outcomes. Continuous activity might lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

In September, the average daily maximum UV index in Gantt, Alabama, is 6. A UV Index of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for ordinary individuals.Note: A maximum high UV index of 6 in September translates into the following recommendations:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
