Weather in September
Temperature
The arrival of September coincides with an average high-temperature of a still tropical 34.4°C (93.9°F), indicating a minimal shift from August's 34°C (93.2°F). Yaye experiences an average low-temperature of 25.5°C (77.9°F) in the month of September.Heat index
The heat index value during September is computed to be a life-threatening hot 48°C (118.4°F). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
