September weather forecast
Aleg, Mauritania

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.

Heat index

In September, the heat index is estimated at a burning hot 46°C (114.8°F). Attention: Heat exhaustion and heat cramps are quite likely. Heatstroke becomes a risk with continued exertion.
Understand that the heat index values take into account shaded locations and mild winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 highly critical to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
