Weather in September
Temperature
The average high-temperature for September is a hot 32.5°C (90.5°F), closely aligning with the temperature of the preceding month. Throughout the month of September, Ghomrassen reports a steady low-temperature average of 23.7°C (74.7°F).Heat index
In September, the average heat index is computed to be a torrid 36°C (96.8°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.The standards for the heat index are set for locations in shade and under light breezes. 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', binds temperature metrics with humidity values to give a sense of the actual warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
