September's average heat index is appraised at a tropical 87.8°F (31°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much.
