During September, the heat index is evaluated at a hot 86°F (30°C). Prolonged exposure and physical activity might induce exhaustion, potentially causing heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
