Weather in September

September, the first month of the autumn in Carthage, is still a hot month, with an average temperature fluctuating between 86.2°F (30.1°C) and 65.3°F (18.5°C).

Temperature

Carthage's weather subtly changes with the onset of September, barely falling from 91.9°F (33.3°C) in August to a still tropical 86.2°F (30.1°C). In September, the nighttime temperature lowers to an average of 65.3°F (18.5°C).

Heat index

The average heat index in September is estimated at a sweltering 96.8°F (36°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. 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 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
