The ski season runs from December through March, though reliable snow cover varies from year to year. At this latitude and altitude, the snowfield can be excellent or thin depending on precipitation — it is worth checking conditions before making the drive from Marrakech specifically for skiing. The best ski conditions are typically in January and February.
Outside ski season, the plateau is accessible from April through November and makes an excellent escape from the Marrakech heat. In summer the temperature at 2,600 metres is 15–20 degrees cooler than in the city. The road can be impassable in heavy snow; check conditions in winter if travelling by car. Spring (April–May) and autumn (September–October) offer ideal hiking weather.
