Cooling Degree Day - CDD
To calculate the CDD, take the average of a day's high and low and subtract 65. For example, if the day's average temperature is 80oF, its CDD is 15. If everyday in a 30 day month had an average temperature of 80oF, the month's CDD value would be 450 (15 x 30). The nominal settlement value for its month's weather derivative contract would therefore be $9,000 (450 x $20).
