Snow Falls in the Sahara Desert
On February 18, 1979, a freak storm dropped snow on the Sahara Desert in Algeria — the first snowfall in living memory in one of the hottest places on Earth.
The forecast called for another dry desert day. The Sahara got a snowstorm instead. On February 18, 1979, snow fell on the world's largest hot desert — an event so unlikely that many people refused to believe it happened at all.
The snow came to southern Algeria, commonly reported near the town of Ain Sefra, known as the "Gateway to the Desert." A mass of frigid air had pushed south from Europe, colliding with the desert atmosphere and sending nighttime temperatures plunging far below freezing. By morning, residents woke to an impossible sight: white dunes where orange sand should have been.
The storm lasted only about half an hour, and the snow melted quickly under the desert sun. But its brevity made it no less astonishing. The Sahara, covering some 9.2 million square kilometers across North Africa, is defined by heat — daytime temperatures can top 50°C (122°F). Yet desert nights can turn bitterly cold, and on that February morning in 1979, every ingredient lined up: freezing air, moisture, and elevation.
Ain Sefra sits about 1,000 meters above sea level in the Saharan Atlas mountains, where winter nights can be brutally cold even when afternoons bake. That elevation, plus the invading Arctic air, was enough to turn a desert morning into something out of a fairy tale: red dunes frosted white, palm fronds edged with ice.
At the time, it was the first snowfall in living memory in that part of the desert. When snow fell near Ain Sefra again in December 2016, news reports called it only the second such event in living memory — the previous one being February 18, 1979. Light dustings have touched the area a handful of times since, but the 1979 storm remains the legendary one, the benchmark every later flurry is measured against.
Since then the desert has teased forecasters again — light dustings near Ain Sefra in 2016, 2017, 2018, and 2021 — each one greeted with the same disbelief and delight. But none has matched the legend of the morning the Sahara turned white.
February 18, 1979 matters as a vivid reminder that Earth's climate is full of surprises. The hottest desert on the planet can wear a coat of white, if only for half an hour — proof that even the most familiar landscapes can still astonish us.
