If the mean temperature for the day is, say, 5 degrees higher than 65, then there have been 5 cooling degree days. On the other hand, if the weather has been cool, and the mean temperature is, say, 55 degrees, then there have 10 heating degree days (65 minus 55 equals 10).
Why do we want or need to know the number of "degree days?"
It is a good way to generally keep track of how much demand there has been for energy needed for either heating or cooling buildings. The cooler (warmer) the weather, the larger the number of "heating (cooling) degree days"... and the larger the number of heating (cooling) degree days, the heavier the demand for energy needed to heat (cool) buildings.
Degree day calculations are made at the end of each day and sent out the following morning in a product called "Climate Report". Reports are made for Atlanta, Athens, Columbus and Macon and are available on the web. Select "Daily Climate Report (CLI)" under "Product", the location of interest, the time frame of interest, and then click on the yellow "GO" button". Degree day information is located about midway down the page that comes up.
