The data for Greenwich, CT 06830 may also contain data for the following areas: Greenwich
Annual Heating Degree Days (HDD): A form of Degree Day used to estimate energy requirements for heating. Typically, heating degree days are calculated as how much colder the mean temperature at a location is than 65°F on a given day. For example, if a location experiences a mean temperature of 55°F on a certain day, there were 10 HDD that day because 65 - 55 = 10, according to the National Weather Service.
Annual Cooling Degree Days (CDD): A form of Degree Day used to estimate energy requirements for air conditioning or refrigeration. Typically, cooling degree days are calculated as how much warmer the mean temperature at a location is than 65°F on a given day. For example, if a location experiences a mean temperature of 75°F on a certain day, there were 10 CDD that day because 75 - 65 = 10, according to the National Weather Service.
Mean Sky Cover: reflects the approximate amount that the sky is covered with clouds, sunrise to sunset on a scale of 0 to 10
Index score: (100 = National Average) for an area is compared to the national average of 100. A score of 200 indicates twice the national average, while 50 indicates half the national average. Note: A higher Weather Index score represents better overall weather (higher number good). A higher Hail, Hurricane or Tornado Index means the chance of that weather event is higher (higher number bad).
