Heat index

August's heat index is calculated to be a tropical 86°F (30°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.
Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
