Note: The heat index, also known as 'feels like' or 'felt air temperature', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations.
