Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children.
