The highest temperature ever measured on Earth was when Death Valley, California hit a sizzling 134°F in July 1913. The record has held, despite skyrocketing global temperatures—but on June 29, the Iranian city of Ahvaz gave it a run for its money when it reached 129°F, according to USA Today.
The phenomenon broke multiple national and world records: It’s Iran’s highest temperature ever recorded (the previous was 127.4°F), it’s the highest recorded June temperature in Asia, and it’s also one of the world’s hottest-ever reliably measured temperatures, according to France’s national weather service. If you factor in humidity, the heat index hit 142°F. Luckily for Ahvaz residents, the high temperature for the next day is a (slightly) cooler 119°F.
Summer 2016 was the hottest season ever recorded—but judging from recent weather trends, it looks like this summer is slated to be yet another for the books. In America, for example, a record heat wave in the Southwest grounded planes in June as temperatures in Phoenix spiked above 118°F. Meanwhile, in late May, temperatures were higher in Scotland than in some parts of Africa.
