The U.S. cities that need the most heating: Ranked by normal heating degree days a year (base 65°F), NOAA 1991-2020

Which U.S. cities need the most heating?

The first ten: Anchorage, AK (9,979 HDD), Grand Forks, ND (9,533 HDD), Duluth, MN (9,115 HDD), Fargo, ND (8,806 HDD), St. Cloud, MN (8,490 HDD), Bismarck, ND (8,471 HDD), Bozeman, MT (8,245 HDD), Eau Claire, WI (7,923 HDD), Rochester, MN (7,856 HDD) and Idaho Falls, ID (7,792 HDD). At the other end of the list is Honolulu, HI (0 HDD).

Method: each place is measured at the NOAA station that keeps its climate record (named in the table); "=" marks a tie at the shown precision. The ranking compares places of 50,000 or more people so that small towns with a single remote station do not lead the list; every other place's figure is on its own page.
