September weather forecastAleg, Mauritania

Weather in September

September experiences a continuation of the monsoon trend with 22mm (0.87") of rainfall, although the number of rainy days diminishes slightly. The heavy cloud cover translates into coolness in the air, with temperatures dipping to the late twenties during nights. A drop in relative humidity combines with a slow decline in temperature from the high of 38.9°C (102°F). Simultaneously, the total daylight hours start to decelerate. Reflecting on these conditions, September proves to be an ideal transitional period from the monsoon to the drier seasons in Aleg, Mauritania.

Temperature

As August transitions into September, the average high-temperature rests at a still fiery hot 38.9°C (102°F), maintaining a close resemblance to the previous month. Throughout September, Aleg encounters an average temperature drop to a warm 29.2°C (84.6°F).

Heat index

The heat index for September is computed to be a blazing hot 46°C (114.8°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Refrain from exposing skin and eyes. Without protection, they can get damaged rapidly. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
