The average daytime temperature is 100°F, while at night the average temperature is 25°F. This large temperature difference is due to low amount of moisture in the desert air.The town of Ain Sefra, on the edge of the Sahara desert, was hit by icy weather last week - and even snow. Snowfall is very rare in the Sahara, despite the fact that it can be cold at night - because there's rarely enough water around for any kind of precipitation.
