Weather in September
Temperature
Mansura starts September with an average high-temperature of a still hot 87.4°F (30.8°C), hinting at a minimal fluctuation from August. The average temperature during September nights dips to a pleasant 68.5°F (20.3°C).Heat index
September's heat index is appraised at a very hot 102.2°F (39°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', quantifies the warmth felt when relative humidity is considered. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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 innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. 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. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
