Weather in September
September indicates a steady shift towards a drier climate as the rainfall drops to 111mm (4.37"), albeit still on the high side. A distinctive September feature is a decrease in wind speed to 5.8km/h (3.6mph), the lowest seen in the year. This decrease in wind speed, accompanied by decreasing rainfall, signals the gradual withdrawal of the rainy season. Despite the remaining humidity and cloud coverage, the gradual change towards drier weather makes conditions more comfortable.Temperature
The ushering in of September brings an average high-temperature of a still warm 29.5°C (85.1°F), closely mirroring the 28.5°C (83.3°F) of August. Tchitchao experiences an average low-temperature reading of 22°C (71.6°F) throughout September.Heat index
During September, the heat index is appraised at a very hot 37°C (98.6°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
