This one is a little controversial.
In 1922, El Azizia, a small town in Libya, secured the record for the hottest temperature ever recorded, a blazing 136.4 degrees Fahrenheit. With this distinction, El Azizia usurped California's Death Valley, which had previously claimed the highest temperature at 134 degrees Fahrenheit in 1913.
However, in 2012, the World Meteorological Organization determined that El Azizia's measurement had been flawed, and returned the title for the hottest place on earth back to Death Valley.
Especially in the summer months, this valley sees temperatures as high as 120 degrees in the shade, with “lows” coming in at 90 degrees at night. Yet despite its sizzle, it offers plenty of reasons to visit.
