Throughout August, the heat index is computed to be a hot 86°F (30°C). Ongoing activity coupled with exposure often results in weariness and could induce heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance 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.
