Heating Degree Days are a measure of how cold your climate is. Heating Degree Days are not calculated from June through August. Heating Degree Days are a measure of the coldness of the weather experienced, based on the extent to which the daily mean temperature falls below a reference temperature (65° F). The following table lists the 30-year seasonal normal heating degree days and the actual heating degree days for the 1998-99 and 1997-98 heating seasons for many locations throughout Colorado. Average temperature maps can wash out days or weeks of hot and cold extremes that are important for things like energy planning and crop risk assessment. Heating degree days are used as an indicator of space heating energy requirements. The average annual heating degree days for a 30-year period using observations from the National Weather Service cooperative observer network. If the average outside temperature for a day is 1 degree less than the inside temperature, then you would accumulate 1 degree day on that day. The daily station normals from the National Climatic Data Center (NCDC) were corrected on June 28, 2003. Be sure to click on the 24-hour trends map from the dropdown as well. Heating and Cooling Degree Days are only available in contour format. Please note that the maps are based on raw data from the U.S. ASOS Network and the data have not been quality controlled. Click on a month for daily values plus daily Wet Bulb Temp (beginning 4/23/20) The user will be prompted to enter the state under consideration, and then will be presented with a list of Zip Codes for that State.

This online calculator pulls weather station data--including heating and cooling degree days (HDD and CDD)--from more than 900 weather stations around the United States and Canada. This system provides access to HUD's heating degree database. Figure Projected linear trend in heating (HDD) and cooling degree days (CDD) over the period 1981-2100 under two scenarios These maps show the trend in heating degree days (left) and cooling degree days (right) from 1981-2100 for all EEA member and cooperating countries, based on the median of an ensemble of 11 EURO-CORDEX simulations. Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. The data was re-run and the correct values are now in the archives. Jake Crouch explains how degree-day maps can bring back the details. According to the graph and data table below, over the last forty–six years, 2011/2012 was the warmest year with 5286 heating degree days, and 1978/1979 was the coldest year with 7440 heating degree days. Heating Degree Day Help. For example, on a day when the mean outdoor dry-bulb temperature is 35°F, there would be 30 degree-days … Use the weather normalization data here to adjust your building's or industrial plant's energy usage data for changes in weather.
