The heat index value for August is computed to be a hot 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'feels like', takes into account both air temperature and humidity to illustrate what people actually feel. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are especially vital to 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.
