Ouona, Burkina Faso

The first month of the autumn, September, is also a hot month in Ouona, Burkina Faso, with an average temperature ranging between max 32.9°C (91.2°F) and min 23.4°C (74.1°F).

Temperature

The onset of September manifests an average high-temperature of a still hot 32.9°C (91.2°F), demonstrating a minor variation from the preceding month. The low-temperature averages to a moderately hot 23.4°C (74.1°F) during the nights of September.

Heat index

The average heat index in September is estimated at an extremely hot 44°C (111.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Take into consideration that the heat index values are calculated for 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 'real feel' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing 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.

For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
