The heat index value for September is estimated at a torrid 102.2°F (39°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.
