Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children.
