The best time of year to visit the Merzouga desert for camel trekking is typically from March to May and from September to November. During these months, the weather is more moderate, with daytime temperatures ranging from 20°C to 30°C (68°F to 86°F), making it ideal for outdoor activities like camel trekking.
Summer months (June to August) can be extremely hot, with temperatures often reaching above 40°C (104°F), which can make trekking less comfortable, especially during the day. However, early morning and evening camel treks are still possible during the summer months, when temperatures are cooler.
Winter months (December to February) are cooler, with temperatures dropping to around 5°C to 10°C (41°F to 50°F) at night, but daytime temperatures are pleasant, making it another great time for camel trekking, though it can get quite cold at night.
