Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children.
