Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual.

Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less.
