Best Time to Visit the Sahara Desert in Morocco (Month-by-Month)

The best time to visit the Sahara Desert in Morocco is March to May or late September to November, when daytime highs sit in the comfortable 20–28°C (68–82°F) range and nights in the dunes are cool rather than bitterly cold. Visit in July or August and you'll deal with midday temperatures well above 40°C (104°F); visit in December or January and be ready for near-freezing desert nights.

Spring (March–May): The Best All-Round Window

This is the season we route the most travelers through Merzouga on our 8 day Sahara tour. Days are warm and dry, nights in a proper bivouac camp are pleasant with a few extra layers, and the light on the Erg Chebbi dunes at sunrise and sunset is at its sharpest thanks to clearer spring air. The one thing to watch for is the occasional spring windstorm, which can whip up sand for a day or two — rare, but worth packing a scarf for regardless of season.

Summer (June–August): Beautiful but Brutal at Midday

Summer in Merzouga is genuinely hot — 40–45°C (104–113°F) at midday is normal, and the sand itself gets hot enough that closed shoes matter more than sandals. That said, mornings and evenings are still lovely, camel treks are scheduled around sunrise/sunset specifically to avoid the worst heat, and desert nights actually cool down enough to sleep comfortably in a well-ventilated tent. If summer is your only window, it's still worth going — just adjust expectations for the hours between 11am and 4pm.

Autumn (Late September–November): Our Second Favorite Window

Almost a mirror of spring, with slightly warmer nights in late September tapering to crisp, clear evenings by November. This is also grape and date harvest season in the Ziz Valley you drive through en route, which adds some nice roadside stops most itineraries don't plan for but our drivers know well.

Winter (December–February): Cold Nights, Clear Skies, Fewer Crowds

Winter days in the Sahara are often pleasantly mild — 18–20°C isn't unusual — but nights regularly drop close to freezing, and camps rely on wool blankets and warm layers rather than air conditioning working in reverse. The upside: near-zero humidity and minimal light pollution make winter nights some of the best stargazing conditions of the year, and Erg Chebbi is noticeably quieter than in high season.

Our Take

If your dates are flexible, build your trip around late March–April or October–November. If they're not, don't let a summer or winter date stop you from going — every one of our itineraries, including the 15 day route with a full Sahara exploration day, is timed around sunrise and sunset activities specifically so the heat or cold of midday and midnight matter less than you'd think.
