When we recommend sun-soaked, warm-weather destinations - say, on the beach or in the jungle – the daily temperature usually tops off at 90 F. Anything above this is just unpleasant. Some places, however, are worth seeking out even though they're so blistering hot you'll have to prepare yourself to be uncomfortable. For these 10 worthy hot spots – with average temperatures well over 100 F – bring lots of water, sunscreen, a good hat, and, if you can help it, have a room with air conditioning.
Lut Desert, Iran
Researchers analyzing data gathered via satellite found that the Lut Desert (Dasht-e Lut) has the highest surface temperature ever recorded, a blistering 159.3 F. Their analysis of the satellites' "land skin temperature" readings around the world had the Iranian desert at the top of the list for five of the seven years studied. The Lut's baking salt flats are bordered by massive dunes shooting hundreds of feet into the air, including the world's tallest sand pyramid, which tops out at about 1600 feet.
