Sahara Desert Morocco Weather: Month-by-Month Guide to Merzouga and Zagora

Sahara desert Morocco weather surprises almost everyone who visits. Travelers pack for heat and then find themselves wrapped in blankets around a campfire, or they come in winter expecting cold and spend the afternoon in a T-shirt. The desert does both, often within the same 24 hours.

Pair this with our Merzouga desert guide to plan the best month for your camel trek.

Our drivers make the run to Merzouga and Zagora year-round, so this guide combines long-term climate averages with what we see on the ground each season. Use it to choose your month, set expectations for the camel trek, and pack the right layers.

Quick answer: The most comfortable months in Morocco’s Sahara are March to May and October to November, with daytime highs of roughly 23 to 30°C (73 to 86°F). Summer days often pass 40°C (104°F), while December and January nights in Merzouga average around 4 to 5°C (39 to 41°F) and can feel colder in the dunes.

Sahara desert Morocco weather: why days are hot and nights are cold

The air over Erg Chebbi and the Draa Valley is extremely dry and the sky is clear most of the year. Without humidity or clouds to trap heat, the sand warms fast under the sun and loses that heat quickly after dark. A 15°C (27°F) drop between afternoon and pre-dawn is normal, and the dunes, sitting away from buildings and asphalt, usually feel a few degrees colder than the town averages below.

Merzouga weather month by month

Merzouga sits at the edge of the Erg Chebbi dunes in southeastern Morocco. These are typical monthly averages for the area; individual days can be hotter, colder or windier.

Rain is rare in every month, falling on only a few days per year on average. When it does come, usually as a short thunderstorm in late summer or autumn, it can be dramatic: in September 2024 unusual storms flooded parts of southeastern Morocco and briefly filled dry lake beds near the dunes.

Zagora and the Draa Valley: a different desert

Zagora is the gateway to the southern desert around M’Hamid and the remote Erg Chigaga dunes. Its climate is broadly similar to Merzouga’s, with long-term averages showing a hot season from roughly early June to mid-September, when highs stay above 37°C (99°F), and July highs averaging around 42°C (107°F).

• Cool season: from late November to late February, daytime highs sit below about 23°C (73°F) and January nights average around 4°C (40°F).
• Wind: long-term data show May as the windiest month and December as the calmest.
• Rain: rare, with November slightly wetter than other months.
• Getting there: Zagora is closer to Marrakech than Merzouga, but Erg Chigaga involves a long off-road drive from M’Hamid, so plan it as a two- or three-day trip.

Which desert should you choose by season? In practice the weather difference between the two is small. Merzouga offers taller dunes, more camp choices and easier access, while Zagora suits short trips from Marrakech. Base the decision on time and the scenery you want, then use the temperature table above for either area.

Sandstorms and wind in the Moroccan Sahara

Sandstorms are the weather question we hear most. Full-scale storms that block out the sun are uncommon, but windy days that lift sand off the dunes are part of desert life, especially in spring.

When winds are most likely

• Late February to May is the windiest period, with May often the peak.
• The Chergui, a hot, dry easterly wind, can push temperatures sharply higher and carry dust, mostly in spring and summer.
• Winds usually build in the afternoon and calm down at night, so sunrise is often the most still and clear time in the dunes.

What happens on a windy day

Camel guides from the local Amazigh communities read the wind well and will shorten or delay a trek if needed. Wrap a cheche (the desert turban) over your nose and mouth, wear sunglasses rather than contact lenses, and keep cameras in a zip bag. Camps are built to handle wind, and storms normally pass within hours.

Best time to visit the Sahara in Morocco

Choosing your month comes down to how you handle heat and cold. When guests ask us about Sahara desert Morocco weather, this is the short version we give:

• Best overall: October, November, March and April, with warm days and comfortable nights.
• Best for photographers: November to February, when the air is clearest and the low winter sun lights the dunes in deep orange.
• Best for budgets: June to August, when demand is lower, as long as you rest through the midday heat.
• Busiest: Easter, late December and early January, when camps fill early.
• During Ramadan: expected around February 8 to March 9, 2027, the desert weather is mild and camps operate normally, though some roadside cafes close by day.

Pair your desert dates with the rest of your route. The 3-day Marrakech to Merzouga desert tour works in any season, and our guide to the best desert activities in Merzouga explains which activities suit hot or cool months.

What to pack for the Sahara, season by season

All year

• A cheche or large scarf for sun, sand and wind
• Sunglasses with UV protection, high-SPF sunscreen and lip balm
• A small daypack for the camel ride, since large suitcases stay in the vehicle
• Closed shoes or sandals with straps; bare feet are fine on cool sand, but not at midday in summer
• A headlamp, wet wipes and a refillable water bottle

October to April

• A warm fleece or down jacket and a hat for evenings and sunrise
• Thermal base layers if you sleep cold; camps provide heavy blankets
• Warm socks to wear in the tent

May to September

• Loose, light-colored long sleeves and trousers in cotton or linen
• A wide-brimmed hat and electrolyte sachets
• A light layer for the night; even in summer the desert breeze can feel cool after midnight

Weather on the road to the desert

The dunes are only half the story. Every route to Merzouga or Zagora crosses mountains, and the weather there can be very different from the desert forecast.

• From Marrakech: the Tizi n’Tichka pass in the High Atlas climbs to about 2,260 meters. Between December and March, snow occasionally closes it for a few hours, and our drivers check road conditions the evening before departure.
• From Fes: the road through Ifrane, Azrou and Midelt crosses the Middle Atlas, where winter mornings are often below freezing and the cedar forests can be snowy.
• In summer: the Draa and Ziz valleys are hot by late morning, so we leave early and stop in shaded oases rather than driving through the midday heat.

This is one reason a desert trip feels best over three days or more. Splitting the drive with a night in the Dades Valley or the Todra Gorge means you arrive at the dunes rested and in daylight, ready for the camel ride at sunset, whatever the season.

Safety in extreme heat and cold

Drink more water than you think you need, especially on the long drive from Marrakech or Fes. In summer, our drivers schedule camel rides for late afternoon and sunrise and keep the middle of the day for shade and rest. In winter, the risk is the opposite: guests underestimate the cold at 5 a.m. on a dune top. Check current conditions and official advice, such as the UK government’s Morocco travel advice, before you go, and the official Morocco tourism website for regional events.
