For September, the heat index is computed to be a hot 30°C (86°F). With extended exposure and activity, one might feel exhausted and experience heat cramps.Heat index determinations are made taking into account the shade and light air movements. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
