World's Hottest Places

The highest shade temperature on record is 58 degrees in September 1922 at Al'Aziziyah in the Sahara Desert in Libya. Nearly as hot was 56.7 degree Celsius recorded in Death Valley in California, in July 1913.

You might expect the hottest places to be on the equator. Although equatorial lands are hot all year, they are also very cloudy. The hot deserts are near the tropics where the sun is overhead in midsummer. Because there is very little rain, there is very little cloud, so it is sunny and hot all day.

The eastern Sahara has more sunshine that anywhere else: sunshine has been recorded for 4,300 hours in a year. That is an average of 11 hours, 47 minutes per day. So it is not surprising that the highest temperature on record occurred in the Sahara.
