The author calculated the heating degree days (t<SUB>0</SUB>= 8°C;t<SUB>e</SUB>=12°C), the first day and the last day of heating over Hokkaido, from the normals of daily mean temperature. As the normals are not satisfactory statistical data, for the purpose of planning of heating, he showed the fluctuations in long range average of the heating degree days and their standard deviation, observed minimum for 8 main stations, covering the last 30 years, as a sample.
