For most parts of September, the heat index is calculated to be a tropical 86°F (30°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
