This was a brutally hot summer for many parts of the globe, including sections of the U.S.
Several American cities set or tied records for the single hottest day since record-keeping began. Most of these scorching days occurred within a one-week period in the middle of July.
Here is a roll call of U.S. cities that sweltered as the thermometer rose to the highest level ever recorded in those places.
Marathon, Florida
Population: 9,857 as of 2022
Record-high temperature: 99 degrees Fahrenheit on July 13 and July 24, 2023
These 99-degree days in this Florida Keys city tied the all-time high record there — for any day — previously reached in June 1972 and July 1987.
Las Vegas, New Mexico
Population: 13,053 as of 2022
Record-high temperature: 100 degrees Fahrenheit on July 18, 2023
In July, this town — which is located about 65 miles east of Santa Fe — recorded its first-ever 100-degree temperature since records began in 1940.
Grand Junction, Colorado
Population: 68,034 as of 2022
Record-high temperature: 107 degrees Fahrenheit on July 17, 2023
The all-time warmest day ever in Grand Junction this past July marked a tie with a day in July 2021.
Gallup, New Mexico
Population: 20,932 as of 2022
Record-high temperature: 101 degrees Fahrenheit on July 17, 2023
The hottest day ever in Gallup tied a record first set in June 2016.
Reno, Nevada
Population: 273,448 as of 2022
Record-high temperature: 108 degrees Fahrenheit on July 16, 2023
The all-time high temperature on July 16 matched the record first set in 2002 and also reached on two days in 2007.
Kingman, Arizona
Population: 34,918 as of 2022
Record-high temperature: 114 degrees Fahrenheit on July 15, 2023
The day that Kingman hit its all-time hottest day was a scorcher for several Southwestern cities. On July 16, five cities — including Las Vegas, Nevada, and Salt Lake City — came within 1 degree of their hottest days on record.
However, Kingman was the only city to actually record an all-time record high.
