August's average heat index is computed to be a tropical 89.6°F (32°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.The heat index's values are generally associated with conditions in shade and light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
