Merzouga Weather by Month and the Best Time to Go

Temperatures by Season at Errachidia

The table gives the long-term averages for Errachidia, the nearest weather station to Merzouga with published 1991-2020 normals. The dunes sit lower and further into the desert, so treat the figures as a guide, then check a live forecast a few days before you leave.

Reading a Desert Forecast

The gap between day and night is the number that matters. An October day of 26.8 C with a night of 14.2 C at Errachidia means a shirt on the afternoon camel ride and a fleece by the campfire. Look at wind too.

A breezy afternoon lifts sand on the dunes, while sunrise is usually the calmest hour.

Merzouga Weather by Season

The table groups the months by season, with the rain figures Errachidia records and what each season means for a night at a desert camp in Erg Chebbi.

September, November, December and February

September opens the autumn season, with summer heat easing week by week. November nights average 7.7 C at Errachidia, so a warm layer is essential. December and February are winter months: days on the dunes stay pleasant, but the night in a tent turns cold and the drive over the mountains takes more care.

The Errachidia to Midelt to Merzouga leg alone covers 303.0 km and 4 h 20 min on the tourist office's Desert Break route, so winter weather on the road matters as much as weather in the dunes.

How Much and When

Errachidia records about 133 mm of rain a year. October is the wettest month at 20.8 mm and July the driest at 3.1 mm. Showers do reach the dunes, usually short and followed by clear sky.

On most days the chance of rain is low, and July averages only 3.1 mm at Errachidia.

When Rain Matters

The risk is on the mountain roads, not at camp. The UK FCDO says flash flooding in mountains and near rivers can make walking and driving dangerous, mainly in winter, and that secondary routes and mountain roads can be especially hazardous in poor weather. If heavy rain is forecast in winter, a 3-day tour such as the Marrakech to Merzouga 3-Day Desert Tour with Camel Trek at $114.05 per person splits the drive over more daylight than a 2-day trip.

From Sunset to Sunrise

The camel ride into camp starts near sunset and the ride back starts before sunrise, the two coolest parts of the day. At Errachidia the October night averages 14.2 C and the January night 2.0 C, with a recorded minimum of -8.1 C. Add the breeze on a camel's back and the dune tops, which rise up to 150 m above the surrounding plain, and a fleece is the item you will use most.

In winter, choose a camp tier with care. The 3-Day Merzouga Desert Tour from Marrakech with a Luxury Camp at $148.26 has a private bathroom in the tent, so there is no cold walk outside at night.

Picking the Right Length

The table sets each tour length next to how it handles the weather, with per person prices from each listing. The full Marrakech to Merzouga tour comparison adds camps and return cities.

Weather Risks and Fixes

The UK FCDO warns that poor lighting makes night driving dangerous, so a tour that reaches the dunes in daylight is the safer choice in winter, when days are short. Flash flooding is mainly a winter risk on mountain roads. FCDO also notes that altitude sickness is a risk in parts of Morocco.

If someone feels unwell, the ambulance number is 150, and pharmacies are open 24 hours in every city and district. Public health facilities offer limited care, while private clinics work to a higher standard, so travel insurance is worth having.

The Desert Night Bag

For a night that falls to 14.2 C in October and near 2.0 C in January at Errachidia, bring a warm top, long trousers, a scarf for wind and sand, sunglasses and sunscreen. Desert air is dry, so lip balm and water help.

The Erg Chebbi dunes run about 28 km north to south. Walking up one for sunrise means soft sand, so closed shoes or sandals you can empty are better than flip-flops. Camps include dinner and breakfast, so food is covered for the night.
