August's average heat index is appraised at a tropical 87.8°F (31°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
