Weather in September
Temperature
With the onset of September, the average high-temperature stands at a still tropical 30.5°C (86.9°F), closely aligned with August's 30.2°C (86.4°F). An average nighttime temperature of 23.7°C (74.7°F) is noted during the month of September.Heat index
The heat index for September is computed to be a fiery hot 39°C (102.2°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely significant 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.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
