Degree Days Help Track Temperature

More weather information from AgriMet -- daily weather data, crop water use charts, and related information

One way we help customers make sense of their energy use is by keeping track of degree days. It is a way to measure how much the outside temperature fluctuates and how much work your home heating or cooling system has to do.

Degree days measures the difference (above and below) between the day's temperature and 65 degrees F., and keeps a running total for the month. The lower the number, the closer the average temperature was to 65 degrees. The higher the number, the wider the gap between the outside temperature and 65 degrees. To learn more about degree days, contact Nadine Huxley, Klickitat PUD's Customer Services Manager. You can call her at 509-773-7609 or toll-free at 800-548-8357.
