The Sahara Desert is often associated with extreme heat and scorching temperatures, but is it also the coldest desert on Earth? Surprisingly, the answer is no.
While the Sahara is undoubtedly one of the hottest places on the planet, with temperatures regularly reaching over 100 degrees Fahrenheit (38 degrees Celsius), its classification as a desert is primarily based on its annual rainfall. Deserts are defined by their arid climate, with very little precipitation. The Sahara receives less than 3 inches (7.6 cm) of rainfall per year, making it one of the driest places on Earth.
However, when it comes to cold temperatures, the Sahara Desert is not the first place that comes to mind. The honor of the coldest desert on Earth goes to the Antarctic desert, a vast icy wilderness that spans the continent of Antarctica. With average temperatures dropping well below freezing, reaching as low as -128.6 degrees Fahrenheit (-89.2 degrees Celsius), the Antarctic desert is truly the epitome of cold.
That being said, the Sahara Desert does experience large temperature fluctuations between day and night. During the day, the scorching sun can raise temperatures to unbearably hot levels, but once the sun sets, the desert cools down significantly. The dryness of the air also contributes to these drastic temperature changes, as with little moisture, heat is easily absorbed and released.
