Statistical concept and methodologyCooling degree days can describe the overall need for cooling. For example, the highest temperature in a day was 32°C and the lowest temperature was 19°C. Then, the mean temperature for that day was (32+19)/2 =25.5. The result is above 18°C, so the cooling degree days are 25.5-18 = 7.5°C.
