The best time to visit Merzouga is during the shoulder seasons, specifically from March to May and from September to November, when the weather is most pleasant for desert activities.
During these months, the daytime temperatures are warm and comfortable, typically ranging from 20°C to 30°C, making it ideal for camel treks, quad biking, and exploring the dunes. The evenings are cooler but still pleasant, superb for stargazing and enjoying campfires without the extreme cold of winter or the intense heat of summer.
Travellers looking for an active and comfortable desert experience will find these periods ideal. The mild weather allows for extended time outdoors, whether you're climbing the Erg Chebbi dunes or exploring the surrounding oases. It's also a great time for photography, with clear skies and beautiful light for capturing the vast desert landscapes.
For those who want to avoid the crowds and potentially find better value on accommodation or tours, visiting in late May or early September can be a good option.
