7 Most Astonishing Facts About the Sahara

4. Very few people live in the Sahara

Only around 2.5 million people inhabit the Sahara. When you consider that this is one of the largest deserts on earth, you can appreciate that this is also one of the lowest population densities to be found anywhere. Most of the population clings to the banks of rivers and lakes, and most of them live a nomadic lifestyle as it is necessary to survive in such a harsh climate. So while the Sahara may be an unforgiving and desolate environment, it is certainly a good place to go to get away from it all.

3. Sometimes the Sahara can be quite cold

While the Sahara is classified as a hot desert, sometimes it’s actually quite cold, particularly at night time starting in December and continuing through February. It is not unusual for temperatures to drop below freezing. And once in a great while, heavy snow may even fall as it did in 2016 for the first time recorded in 37 years. The sight of snow-capped sand dunes is certainly an unusual one, but some of the pictures from that December are magnificent.

It is also well worth it to check out pictures of the previous snowstorm from 1979. Some of these photos are just as incredible. The snow was so intense that year that it stopped traffic in the region. That said, it didn’t last very long. Within a few hours it had melted entirely.

Wondering how hot the Sahara gets? During summer, the average high temperatures range to around 40°C. Sometimes they may surge as high as 47°C.

2. The Sahara Desert is anything but lifeless

When you picture a desert, it is easy to imagine nothing but endless miles of sand dunes and barren rocks. But in reality, the desert is a complex ecosystem, and the Sahara is teeming with life. There are estimated to be around 1,200 plant species inhabiting this desert.

There are so many different species of animals and birds. Some of these include gazelles, antelopes, monitor lizards, cheetahs, wild dogs, vipers, and ostriches. Like the human inhabitants of this desert, many of these species are nomadic, migrating in order to follow the water supply throughout the year.

1. The Sahara actually has a number of sub-regions

These sub-regions are known as ecoregions, and are defined according to their different precipitation, temperature, elevation and soil characteristics. Along the west coast for example is the Atlantic coastal desert, which is able to support succulent plants, lichens and shrubs. In the north is the North Saharan steppe and woodlands. Other ecoregions include the Sahara Desert ecoregion, the South Saharan steppe and woodlands, the West Saharan montane xeric woodlands, the Tibesti-Jebel Unweinat montane xeric woodlands, the Saharan halophytics, and the Tanezrouft.

Some of these areas are particularly desolate and devoid of life. The Tanezrouft for example has almost no vegetation. Other areas however have watercourses which run for part of the year as well as rainfall. This is why the South Saharan steppe and woodlands contains pastures, shrublands and even dry forest. Most of the Sahara isn’t even comprised of sand at all.

So now you know more about the Sahara! The third largest desert in the world covers a huge amount of land, and is a very unique place. If you are touring Africa and have a chance, you should definitely visit—the experience is one you will never forget.

Just remember that it is an unforgiving place, and you should come well-prepared.
