The U.S. cities with the most freezing nights: Ranked by nights a year with a low of 32°F or less, NOAA 1991-2020

Which U.S. cities have the most nights below freezing?

The first ten: Flagstaff, AZ (202 nights), Bozeman, MT (198 nights), Anchorage, AK (186 nights), Grand Forks, ND (185 nights), Bismarck, ND (184 nights), Casper, WY (183 nights), Idaho Falls, ID (182 nights), Longmont, CO (178 nights), Parker, CO (177 nights) and Duluth, MN (177 nights). At the other end of the list is Tamiami, FL (0 nights).

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.
