The Sahara Desert's climate has been relatively stable for the past 2,000 years. That said, parts of the Sahara Desert have different climatic conditions than others, particularly when comparing the northern region's arid, subtropical climate with the southern region's arid, tropical climate.
Dry, Subtropical Climate
High-pressure cells at the Tropic of Cancer keep conditions dry and subtropical in the northern Sahara Desert. The hottest temperature on record for this region is 136.4 degrees, but winter evenings can get surprisingly cool, falling to around 55 degrees. Rainy season falls between late winter and early spring; in August, intense storms can create flash floods that bring water to typically arid parts of the desert.
Dry, Tropical Climate
The combined conditions of an unstable marine and stable continental air masses result in an arid, tropical climate in the southern Sahara Desert. Average temperatures are lower here than in the north, particularly at higher elevations. In fact, the highest parts of the southern Sahara Desert get snow during winter. In the western section, the cold current from the Canary Islands creates humidity and fog, but reduces precipitation.
Scarcity of Rainfall
Dryness rather than heat is what makes the Sahara a desert climate. Divergent air masses within the high-pressure system dry the air before fronts can form. Even the subtropical zones near the west see relatively low amounts of precipitation. The Sahara Desert averages under 3 inches of rainfall yearly. Some regions see no rainfall for many years.
Recent Climatic Shifts
In the 2009 article "Sahara Desert Greening Due to Climate Change?" James Owen reports on some gradual changes in the Sahara Desert's climate. He cites an overall shrinking of arid regions due to increasing rainfall. Satellite images of the Sahara Desert show a greening of the semidesert zone running along the Sahara's border. Sections of Chad and Sudan have experienced dramatic increases in the amount and diversity of vegetation growing there. Scientists opine that increased temperatures from global warming might be increasing the desert air's capacity to hold moisture, prompting increased rainfall.
Traveling Through the Sahara
Visiting and traveling through the Sahara is a once in a life time experience. However, before visiting, make sure to be prepared. One of the most popular starting points for visiting the desert is Marrakech, Morocco. However, the city is located about 370 miles away from Merzouga, Moroccowhich is located next to the popular Erg Chebbi sand dunes. Therefore, if looking to experience the desert under the stars it is recommended to at least set aside two days for the trip. Due to the extreme changes in temperature between daytime and nighttime, it is recommended to bring a jacket and pants.
