Spring and autumn first
The Moroccan National Tourist Office recommends spring and autumn for the southern desert. Use that as a starting point rather than a promise of comfortable weather on every departure.
Plan for your whole route
A desert trip also crosses other landscapes. Marrakech departures use the High Atlas; Fes routes use the Middle Atlas. Look at the forecast for your starting city, the mountain corridor and Merzouga, rather than checking one city only.
Ask before choosing a camp
Confirm the camp’s actual heating or cooling arrangements, bedding and bathroom facilities. A package label does not establish which amenities are available.
Leave space in your schedule
Avoid relying on an unconfirmed return time for a same-day flight or train. Choose the route and endpoint first, then arrange onward travel with suitable flexibility.
