September weather forecast
Batie, Burkina Faso

A clear transition from the rainy season to the dry season is indicated in September. It begins with a steep decline in rainfall from its August peak, with precipitation amounts reducing to 123mm (4.84"). Gradually cooler temperatures and receding rainfall mark the onset of the drier months. However, the amount of daylight and the duration of sunshine remain relatively consistent. The wind speed reduces significantly in this month, making the weather considerably calmer compared to the previous rain-dominant months.

Temperature

Batie, Burkina Faso, marks the onset of September with an average high-temperature of a tropical 30.8°C (87.4°F), a subtle shift from August's 29.8°C (85.6°F). An average low-temperature of 22°C (71.6°F) is observed during September nights in Batie.

Heat index

During September, the heat index is appraised at a blistering 41°C (105.8°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
It is crucial to understand that heat index figures are for shade and gentle wind conditions. 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 'real feel' or 'apparent temperature', arises from combining readings of air temperature and relative moisture content. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
