The heat index value during August is computed to be a hot 91.4°F (33°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. 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', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
