As Morocco is bordered with the Atlantic and the Mediterranean oceans from two sides and the desert in the other sides, Morocco’s climate is as varied as its diverse geography. Morocco has wide-ranging geological formations, including a vast coastline, interior lowlands extending into the foothills and highlands of the Rif Mountains and the Middle Atlas and High Atlas ranges which sore up to 13,700 f / 4150 m between the mountain ranges and the Atlantic lie plains and plateaus of fertile agricultural lands. To the east the mountain slopes are much more arid as they drop into the unforgiving desert of the Sahara.  Our Morocco Social Tours itineraries traverse several of these major geographic features. We begin from Tangier, Marrakech, Agadir, Fes or Casablanca on the Atlantic Coast and work clockwise to the interior city of Fez before crossing the Middle and High Atlas mountains to Rissani and the Sahara and then back across the southern section of the high atlas range to Marrakech.

Generally speaking, Morocco's climate is moderate and subtropical, cooled by breezes off the Atlantic and Mediterranean. In the interior the temperatures are more extreme, winters can be fairly cold and the summers very hot. In fact, the further you go from the ocean the more extreme winter and summer temperatures become. Just avoid July and August and you’ll be when the weather is warm and dry. Average summer temperatures in the coastal cities, range from18- 28°C. In the interior, however, highs frequently exceed 35°C.

Weather along the coastal region is tempered by the Mediterranean in the North and the Atlantic Ocean along Morocco’s Western coast near Casablanca and Essaouira. Average daily temperatures range from about 12°C in winter (Nov-April), to 25°C and higher in summer (July-Sep).

Going inland to the northern plateau region, Fez has a continental climate with more extreme temperatures. In summer it can get over 39°C, but generally hovers in the 29-35°C range. Winters, by contrast, can be rather cold with daily temperatures around 16°C and nights dropping to 5°C - 7°C.

Heading due south into the interior lowlands, Marrakesh has an average winter temperature 16°C and summer temperature of 38°C. The hottest months of the year are July and August, but there is little humidity so temperatures are generally bearable. Marrakech and the lowlands of Morocco can become stiflingly hot in summer, easily exceeding 40°C when the desert winds from the Sahara (known as the sirocco or chergui) are blowing. It is sunny nearly all year round, with mild winters. But winter can bring heavy downpours of rain and nights can be in the lower 5°C.

In the Atlas Mountains temperatures can drop below minus or zero Celsius in winter and mountain peaks are snowcapped throughout most of the year. The winter in the north of the country bordering the Mediterranean is wet and rainy, while in the south near Rissani and the Erg Chebbi dunes and the edge of the Moroccan Sahara, it is dry and can be bitterly cold at night. The Atlas Mountain highlands are buried in snow during the winter and serve as a popular reprieve from the hot lowlands in summer. Summer Hiking in the Atlas Mountains is generally sunny and warm and cool at night.

Regardless of when you are traveling to Morocco, it’s best to bring many layers as your trip will involve travel through many different climate zones. A more detailed temperature breakdown and complete packing list is provided to our travelers as a part of our pre-departure travel services.
