1Excludes Alaska and Hawaii. Notes:  -  Degree-days are relative measurements of outdoor air temperature.  Heating degree-days are
deviations below the mean daily temperature of 65- F.  For example, a weather station recording a mean
daily temperature of 40- F would report 25 heating degree-days.  -  Temperature information recorded by
weather stations is used to calculate State-wide degree-day averages based on resident State population.
Beginning in July 2001, data are weighted by the 2000 population.  The population-weighted State figures
are aggregated into Census divisions and the national average.  -  See Appendix C for map of Census
divisions.

temperatures recorded at about 200 major weather stations around the country.
