The U.S. cities with the most 90°F days: Ranked by days a year with a high of 90°F or more, NOAA 1991-2020

Which U.S. cities have the most days over 90°F?

The first ten: Laredo, TX (185 days), Indio, CA (184 days), Casa Grande, AZ (184 days), Maricopa, AZ (183 days), Yuma, AZ (181 days), Tempe, AZ (179 days), Lake Havasu City, AZ (178 days), McAllen, TX (177 days), Mesa, AZ (177 days) and Phoenix, AZ (173 days). At the other end of the list is Anchorage, AK (0 days).

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.
