Weather in September
Temperature
Kepioudou's shift from August to September is accompanied by an average high-temperature of a still tropical 34.3°C (93.7°F), a slight deviation from 33°C (91.4°F). Kepioudou, during the nights of September, registers a substantial plunge from the daytime high, averaging at a pleasant 21.1°C (70°F).Heat index
In September, the average heat index is evaluated at a blazing hot 51°C (123.8°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
