Heat index

Throughout September, the heat index is evaluated at a very hot 98.6°F (37°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

In September, the average relative humidity is 77%.
