Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers.
