September signals the transition from the scorching Egyptian summer towards milder fall temperatures. The city experiences a noticeable plunge in temperature, offering a welcome reprieve after the intense summer months. The shift from September to
October will witness a further decline in temperature and daylight hours. September's temperature is comparatively comfortable, with nights cooling down to 19.5°C (67.1°F) and days heating up to 34.7°C (94.5°F). Despite the fall in temperatures, humidity levels remain stable at 51%.
Temperature
Shifting into September,
Beni Suef records an average high-temperature of a hot 34.7°C (94.5°F), presenting minor fluctuations compared to the previous month. Beni Suef reports a significant contrast between daytime and nighttime temperatures, with an average low of 19.5°C (67.1°F) in September.
Heat index
The average heat index in September is evaluated at a blistering 40°C (104°F). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
