September weather forecast
Leo, Burkina Faso

In September, Leo begins bidding farewell to the rainy season, with the weather increasingly leaning towards drier conditions. The shift becomes evident as rainfall levels directory, and the relative humidity begins falling. The prolonged daylight hours begin to shorten, leaving room for longer evenings and early mornings. The temperature regains its upward momentum, setting a pace for the hotter months to come. The smooth transition from the wet to dry season neatly packages the climatic variations Leo experiences throughout the year.

Temperature

September's advent denotes a minor fluctuation in the average high-temperature to a still tropical 32.4°C (90.3°F) from August's 30.8°C (87.4°F). The month of September records an average low-temperature of 23.2°C (73.8°F).

Heat index

The heat index value during September is computed to be a blistering 43°C (109.4°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
