That definition on Wiki-O-Pedia is awful! Talk about confusing....sheesh!
A degree day is..... take the high and low temps of the day & average them. Subtract that from 65 & the answer is the number of degree days. Example: The high was 50, the low was 10. The average is 30. 65 minus 30 is 35. So that day had 35 degree days.
Fuel companies that deliver use degree days to figure out how much fuel you probably used. The newspapers tell you how many degree days are expected each year in your area. They also tell you how many have actually occurred. The bottom line: Using degree days tells us how cold it usually is compared to how cold this year actually is.
Odd.... I haven't looked for some time.... for this heating season we are almost spot on for average cold. It sure seems like it's been colder than normal! (9 below zero as I type)
