Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees.
