Throughout August, the heat index is evaluated at a hot 86°F (30°C). If exposure and ongoing activity persist, they might induce a state of tiredness and heat cramps.When referencing the heat index, its values are suitable for shady environments and light breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
