Weather in September
Temperature
September experiences an average high-temperature of a still tropical 34.4°C (93.9°F), barely different from August's 34°C (93.2°F). In the month of September, Rheul's average low-temperature falls to a moderately hot 25.5°C (77.9°F).Heat index
The heat index value for September is computed to be a life-threatening hot 48°C (118.4°F). Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. 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. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
