Weather in September
Temperature
September's onset records a minor alteration in the average high-temperature to a still tropical 32.8°C (91°F) from August's 31.3°C (88.3°F). September brings an average low-temperature of 22.5°C (72.5°F) to Bu Kieny.Heat index
The heat index value for September is evaluated at an extremely hot 44°C (111.2°F). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are essentially critical for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
