The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. There is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

On Monday, the average temperature was 62.6 degrees Fahrenheit (17.01 degrees Celsius), breaking a record that lasted only 24 hours.
