Temperature

With the onset of September, the average high-temperature registers at a torrid 35.5°C (95.9°F), subtly different from August's 33.8°C (92.8°F). In September, Ouahigouya reports a consistent average low-temperature of 25.6°C (78.1°F) during the nights.

Heat index

In September, the average heat index is evaluated at an extremely hot 43°C (109.4°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
