The hottest desert in the world is the Lut Desert, also known as Dasht-e Lut, a salt desert located in southeastern Iran, specifically in the Kerman, Sistan and Baluchistan provinces. These regions are reknown for being some of the most arid and hot regions on our planet, with temperatures reaching up to 159 degrees Fahrenheit (70 degrees Celsius).
The Lut desert is the world’s 33rd largest desert; measuring around 480 km long and 320 km wide, with an area of about 51,800 square kilometers, making it one of the smallest “true” deserts out there, and much smaller than the Sahara desert which spans over 11 different countries in North Africa.
Just as impressive in terms of world records, the Lut desert is also the hottest place on Earth with a recorded surface temperature of 70.7 °C (159.26°F), with areas unsuitable for human life.
The site was also listed as a UNESCO World Heritage Site since July 2016.
The Lut desert covers much of the territory of Iran and has a hyper-arid climate with extremely low precipitation and hot temperatures year round.
Climatically speaking, Iran is part of the Afro-Asian desert belt from the Cape Verde Islands off West Africa to Mongolia, whereas geographically speaking, the country consists of a plateau surrounded by mountains and divided into drainage basins.
The largest of these basins is precisely the Dasht-e Lut, followed immediately by Iran’s other great desert, called the Dasht-e Kavir.
During the wet season of spring rains, water flows down from the nearby Kerman Mountains and floods the area, but in a very short period of time it dries up, leaving only rocks, sand and salt.
In addition, in this area, besides sand and dunes, which can be up to 300 meters high, there are also several rocky ridges, as well as numerous gorges and sinkholes.

The hottest desert in the world
The Lut Desert is especially known for being the hottest desert on Earth; in fact, measurements taken by Nasa, between 2003 and 2010, showed that its surface reached a record-breaking temperature of 70.7 °C, the highest ever recorded on our planet.
This is much hotter than the Sahara desert, the largest and most famous hot desert in the world, and broke the previous record set by the Death Valley in the US, which measured 130 degrees Fahrenheit (around 53°C).
Not only that, but the desert recorded the highest overall temperature compared to all other deserts for 5 out of 7 years of recording through satellites.
To be exact, the highest temperature zone in this desert is Gandom Beryan, a plateau covered with solidified lava that is roughly 480 km² wide.
According to local legend, the name Gandom Beryan, which means “toasted grain” in Persian, is said to derive from an incident as a result of which a load of grain was abandoned in the desert and subsequently burned by the heat within a few days.
For all the aforementioned reasons, no human settlement has ever been established in this area of the Lut desert.
