For most parts of August, the heat index is calculated to be a tropical 86°F (30°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 quite important for babies and toddlers.
