The heat index value during September is computed to be a blistering 44°C (111.2°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. 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 the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
