Climate

In area, Morocco's climate is mainly " hot summer Mediterranean " (Csa) and " hot desert " (BWh) zones.

Central mountain ranges and the effects of the cold Canary Current, off the Atlantic coast, are significant factors in Morocco's relatively large variety of vegetation zones, ranging from lush forests in the northern and central mountains, giving way to steppe, semi-arid and desert areas in the eastern and southern regions. The Moroccan coastal plains experience moderate temperatures even in summer.

In the Rif, Middle and High Atlas Mountains, there exist several different types of climates: Mediterranean along the coastal lowlands, giving way to a humid temperate climate at higher elevations with sufficient moisture to allow for the growth of different species of oaks, moss carpets, junipers, and Atlantic fir which is a royal conifer tree endemic to Morocco. In the valleys, fertile soils and high precipitation allow for the growth of thick and lush forests. Cloud forests can be found in the west of the Rif Mountains and Middle Atlas Mountains. At higher elevations, the climate becomes alpine in character, and can sustain ski resorts.

Southeast of the Atlas mountains, near the Algerian borders, the climate becomes very dry, with long and hot summers. Extreme heat and low moisture levels are especially pronounced in the lowland regions east of the Atlas range due to the rain shadow effect of the mountain system. The southeasternmost portions of Morocco are very hot, and include portions of the Sahara desert, where vast swathes of sand dunes and rocky plains are dotted with lush oases.

In contrast to the Sahara region in the south, coastal plains are fertile in the central and northern regions of the country, and comprise the backbone of the country's agriculture, in which 95% of the population live. The direct exposure to the North Atlantic Ocean, the proximity to mainland Europe and the long stretched Rif and Atlas mountains are the factors of the rather European-like climate in the northern half of the country. That makes Morocco a country of contrasts. Forested areas cover about 12% of the country while arable land accounts for 18%. Approximately 5% of Moroccan land is irrigated for agricultural use.

In general, apart from the southeast regions (pre-Saharan and desert areas), Morocco's climate and geography are very similar to the Iberian peninsula. Thus Morocco has the following climate zones:

South of Agadir and east of Jerada near the Algerian borders, arid and desert climate starts to prevail.

Due to Morocco's proximity to the Sahara desert and the North Sea of the Atlantic Ocean, two phenomena occur to influence the regional seasonal temperatures, either by raising temperatures by 7–8 degrees Celsius when sirocco blows from the east creating heatwaves, or by lowering temperatures by 7–8 degrees Celsius when cold damp air blows from the northwest, creating a coldwave or cold spell. However, these phenomena do not last for more than two to five days on average.

Climate change is expected to significantly impact Morocco on multiple dimensions. As a coastal country with hot and arid climates, environmental impacts are likely to be wide and varied. As of the 2019 Climate Change Performance Index, Morocco was ranked second in preparedness behind Sweden.
