Throughout September, the heat index is evaluated at a hot 30°C (86°F). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
