Europe: HDD and CAT

A degree day is a measure of how much a day’s average temperature deviates from 65 degrees Fahrenheit (18 degrees Celsius), a baseline selected by utility companies since furnaces and air conditioners are turned on above and below this benchmark.

In Europe, the CME CAT Index is the accumulation of daily average temperatures over a calendar month, with the accumulation period beginning on the first calendar day of the contract month and ends with the last day of the contract calendar month. Cumulative Average Temperature (CAT) contracts are available for summer months in Europe, allowing businesses to hedge against monthly volatility by tracking average daily temperature in a given city.
