September weather forecast
Yao, Chad

September transitions from the rainy to the dry season in Yao, as the rainfall begins to decrease substantially to 36mm (1.42"), and temperatures start to rise once again. The relative humidity drops from August's 69% to a lesser 56% marking the shifting weather patterns. As the seasons transition, cloud dispersion increases, allowing for more daylight hours despite the lesser number of sunshine days. Wind speeds also witness a slight increase from August, contributing to the evaporation of water and drying out of the environment. September is also when the pressure begins its gradual climb back to its annual peak.

Heat index

During September, the heat index is evaluated at a blazing hot 45°C (113°F). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
