Muslim's holiest city is also the world's hottest city.
Mecca, in Saudi Arabia, is the warmest inhabited place on earth. Its average annual temperature is 87.3 degrees Fahrenheit. In summer, temperatures can reach 122 degrees fahrenheit.
The city is located in Sirat Mountains, inland from the Red Sea, 900 feet above sea level.
On top of the heat, it gets busy. While a little over 1.5 million people live there permanently, more than 2 million pilgrims travel to Mecca annually. Every Muslim, who is able and can afford it, is expected to travel there at least once in their life for the Hajj. Non-Muslims are not allowed to enter Mecca.
For those who live there year-round, winters are a little more manageable. But it never gets cold.
