Manga, Burkina Faso

In September, the pendulum swings back to warmer and drier conditions. The most notable change occurs in the rainfall, with levels dropping markedly to 60mm (2.36"). The cooling trend in temperature reverses as September witnesses an increase to 32.4°C (90.3°F). Despite the lingering humidity, it is a suitable month for travel and outdoor activities. As September wraps up, Manga prepares itself for the scorching October sun.

Temperature

As September takes hold, the average high-temperature is a still tropical 32.4°C (90.3°F), nearly mirroring that of the previous month. Throughout September, an average nighttime temperature of 23.2°C (73.8°F) is experienced.

Heat index

In September, the heat index is estimated at a blisteringly hot 43°C (109.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 hold great significance to children. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. 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 heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes.
