Part of the Sahara was covered with snow on 07 January 2018, despite the desert at times being one of the hottest places on Earth. The snow was reported to be up to 40 cm thick in some places. Although temperatures plummet during the night, snowfall is very unusual in the Sahara because the air is so dry. It is only the third time in nearly 40 years that this part of the desert has seen snow.
Most of the snow had melted by the end of the next day, but luckily the Sentinel-2A satellite happened to be in the right place at the right time to record this rare event from space.
