Heating and cooling degree days

Heating Degree Days (HDD) and Cooling Degree Days (CDD) are based on daily temperature and indicate the level of comfort. The daily values of HDD and CDD were summed for each month and annually and then averaged over the 30-year period 1961-1990. The maps show how these average monthly and average annual values of HDD and CDD vary across Australia. The maps use a temperature BASE of 12°C and 18°C for HDD and 18°C and 24°C for CDD.
