For September, the heat index is calculated to be a tropical 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
