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
The shift into September finds
Beni Suef,
Egypt, at an average high-temperature of a tropical 34.7°C (94.5°F), closely comparable to
August's conditions. In September, a remarkable difference from daytime highs is noted, as Beni Suef records an average temperature of 19.5°C (67.1°F) during the night.
Heat index
During September, the heat index is estimated at an extremely hot 40°C (104°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Heat index determinations are made taking into account the shade and light air movements. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives an indication of how one might feel in terms of heat after considering humidity. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are highly important for children. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
