One of the most notable climate records for July 2017 was the new global record for the hottest single month, which was set in Death Valley, CA. Their average temperature for the month was 107.4 F, the highest at that site since records began in 1911, and the highest single month value measured anywhere on Earth. Death Valley is often one of the hottest locations on Earth every summer, but this is the hottest yet. Previously another monthly measurement, 107.44°F reported at the King Khaled Military City site in northern Saudi Arabia during August 2014, was considered to be the highest, but analysis of their record shows that it was in error.
