Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity.
