In short: December is one of the best months to visit the Morocco desert: bright, dry days around pleasant t-shirt temperatures and near-guaranteed clear skies for stargazing. The catch is the cold: desert nights near Merzouga can drop close to freezing, so you pack for warmth even under an African sun.
What is the weather really like in December?
The Moroccan Sahara sits firmly in the good-season window of October to April, and December lands right in its heart. Daytime in the dunes around Erg Chebbi is usually comfortable and sunny, a world away from the 40C+ furnace of July and August. The story flips after sunset. Once the sun drops behind the dunes, the temperature falls fast, and pre-dawn hours can hover near freezing. On my last December night at Merzouga I wore a fleece, a jacket, and a wool hat to watch the stars, then dived under three thick camp blankets. The upside of that dry, cold air is visibility: December delivers some of the clearest night skies of the year, with the Milky Way stretched from horizon to horizon.
How do I get to the dunes from Marrakech or Fes?
The classic December route is Marrakech to Merzouga and the Erg Chebbi dunes, roughly 560km and 9 to 10 hours of driving, which is why it is sold as a 3-day tour rather than a rushed day trip. That pacing matters more in winter because daylight is shorter, and you want to reach camp before the cold sets in. Coming from the north, Fes to Merzouga is shorter at about 470km and 7 to 8 hours. If you are tight on time, the Marrakech to Zagora run is around 360km and about 7 hours, packaged as a 2-day tour into smaller dunes.

Erg Chebbi or Erg Chigaga in winter?
Erg Chebbi at Merzouga is the postcard Sahara: towering, sculpted dunes reaching about 150m at their tallest, and the most accessible by paved road. That accessibility makes it the sensible December pick, since you can reach camp reliably even on a short winter day. Erg Chigaga, out near M’Hamid, is wilder and more remote, reached only by 4×4 over rough desert tracks. It rewards you with genuine isolation and even darker skies, but the extra travel is a bigger commitment when daylight is limited. In December both are cold at night; Chigaga simply feels lonelier, which is exactly what some travelers are chasing.
What about Agafay near Marrakech?
If you cannot spare three days, the Agafay desert is only about 40 minutes from Marrakech. Be clear on what it is, though: Agafay is a rocky, stone desert of pale rolling hills, not Saharan sand dunes. In December it makes a lovely day or overnight escape with Atlas mountain views often dusted with snow on the horizon, and camps there run fires and dinners under the same clear winter sky. It is the practical choice for a taste of desert nights without the long drive south.
How much does a December desert tour cost?
Prices swing with group size, comfort level, and how much of the trip is private. A shared 3-day Merzouga tour from Marrakech typically falls in the region of 80 to 150 EUR per person, usually covering transport, one or two camp nights, and some meals. Private tours and luxury camps cost more; budget shared trips less. December is shoulder-to-quiet season for the desert compared with the autumn rush, so you often have a little more room to negotiate than in October. Always confirm exactly what blankets, heating, and meals are included before you book, because in winter those details are what keep the night comfortable.
How should I pack for cold desert nights?
Layering is everything. Days invite light clothing, so bring breathable shirts and sunglasses, but nights demand a warm insulating layer, a windproof jacket, a hat, and gloves. Closed shoes and warm socks beat sandals after dark. A headlamp helps around unlit camps, and lip balm plus moisturizer counter the drying air. For more seasonal planning tips, see our related guide.
Frequently Asked Questions
Is December too cold for the Morocco desert? No. Days are pleasant and sunny; only the nights are genuinely cold, near freezing at Merzouga. With proper layers and camp blankets it is very comfortable, and the clear skies are a major bonus.
Does it snow in the Sahara in December? Snow is rare in the dunes themselves, but you may see it on the High Atlas peaks you cross on the drive from Marrakech, which makes for a striking contrast.
How many days do I need? Plan 3 days for Merzouga and Erg Chebbi given the roughly 560km each way. Zagora works as a 2-day trip, and Agafay can be done in a single day or overnight.
Is stargazing good in December? Yes, arguably the best. The cold, dry, cloud-free air gives exceptional clarity, and away from any town lights the Milky Way is vivid.
Should I book ahead for the winter holidays? Yes. Late December around Christmas and New Year is popular, so reserve camps and transport in advance even though December is generally quieter than autumn.
