Most people think of a normal body temperature as an oral temperature of 98.6Â°F (37Â°C) . This is an average of normal body temperatures. Your temperature may actually be 1Â°F (0.6Â°C) or more above or below 98.6Â°F (37Â°C) .
A Degree Day is simply a unit for measuring how cold (or hot) it has been over a 24 hour period. Whenever the average (or mean) temperature is below 65Â°, you have a Degree Day. For example, if during a 24 hour period the high outdoor temperature was 70 degrees and the low was 50 degrees, then the average temperature for that day was 60 degrees - halfway between 70 and 50 degrees. This is 5 degrees less than the base temperature of 65Â°.
