September weather forecast
Nouna, Burkina Faso

As Nouna transitions from August to September, rainfall begins to ease, reducing significantly down to 37mm (1.46"). The wet season starts to show signs of wrapping up, as relative humidity decreases and cloud cover begins to recede. Despite the decline in rainfall, the prevailing temperatures remain relatively cool, a respite from the warmer months at the year's start. Sunshine returns to the forefront, providing warmth and brightness to the dissipating rains. September thus marks the onset of the transition period before the dry season kicks in again.

Temperature

At the start of September, Nouna's average high-temperature reaches a fiery hot 35°C (95°F), subtly different from the preceding month. In September, Nouna experiences an average nighttime temperature of 24.9°C (76.8°F).

Heat index

In September, the heat index is calculated to be a blazing hot 45°C (113°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Regarding the heat index, one should be aware it's determined by shaded settings and mild winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Take special precautions, as unprotected eyes and skin can be burned and damaged quickly. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
