Heating Degree Day Information

Notes about the content on this page:

  • Last updated: 09/09/2021 
  • Source: National Oceanic and Atmospheric Administration, National Weather Service Degree Days Statistics.
  • Annual heating seasons run October through March (seasonal, weekly, and monthly).
  • "Normal" is a 30-year degree day average value for the period 1971-2000, unless otherwise noted.
  • "Degree-days" are relative measurements of outdoor air temperature used as an index for heating and cooling energy requirements. Heating degree-days are the number of degrees that the daily average temperature falls below 65° F. Cooling degree-days are the number of degrees that the daily average temperature rises above 65° F. The daily average temperature is the mean of the maximum and minimum temperatures in a 24-hour period. For example, a weather station recording an average daily temperature of 40° F would report 25 heating degree-days for that day (and 0 cooling degree-days). If a weather station recorded an average daily temperature of 78° F, cooling degree-days for that station would be 13 (and 0 heating degree days).
