Heating Degrees Report
This report is generated by the City of Tacoma for Peninsula Light Company in South Puget Sound. You can use this as a general reference for how hard your heater has to work to keep you comfortable. Many thanks to Penlight for their permission to use this monthly chart.
There is also a free heating degree day report site you can use to compare years based on weather stations near or in your zip code. That site is called weather data depot. weather data depot
