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

Which U.S. cities need the most air conditioning?

The first ten: McAllen, TX (4,989 CDD), Honolulu, HI (4,767 CDD), Phoenix, AZ (4,765 CDD), Indio, CA (4,730 CDD), Yuma, AZ (4,705 CDD), Miami, FL (4,656 CDD), Hollywood, FL (4,640 CDD), Pompano Beach, FL (4,608 CDD), Fort Lauderdale, FL (4,573 CDD) and Brownsville, TX (4,542 CDD). At the other end of the list is Anchorage, AK (8 CDD).

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.
