From day to night how many degrees can the temperature change in the Sahara?

In the Sahara Desert, temperatures can vary significantly between day and night, often experiencing shifts of 30 to 40 degrees Celsius (54 to 72 degrees Fahrenheit) or more. During the day, temperatures can soar above 40 degrees Celsius (104 degrees Fahrenheit), while at night, they can plummet to near freezing, particularly in winter months. This drastic temperature fluctuation is due to the desert's dry air and lack of vegetation, which limits heat retention.
