The honest answer is that the Moroccan Sahara has one real season, and it runs from October to April. Outside that window the desert around Merzouga and Erg Chebbi regularly climbs past 45°C in the shade, and a camel trek or a night in a tent stops being a pleasure and starts being an endurance test. Inside that window, the desert is arguably at its best anywhere on earth: warm days, star-filled nights, and dunes that turn gold, then pink, then violet at sunset.

Quick answer: the short season

If you only read one paragraph, read this one. Book between October and April, and if you can choose freely, aim for late October–November or March–April. December to February is also good but nights in the desert camp get genuinely cold, sometimes close to freezing. Avoid May through September unless you're prepared for daytime heat above 40°C and, in July and August, well above that.

Month-by-month breakdown

  • January: Cold nights (2–8°C), mild sunny days (~18°C). Quiet season, good prices.
  • February: Similar to January, warming slightly toward the end of the month.
  • March: The shoulder season begins — daytime temperatures climb into the low-to-mid 20s°C, nights are still cool but manageable.
  • April: Widely considered the best all-round month: warm days, comfortable nights, green oases after winter rain.
  • May: Heat starts building fast; still workable but afternoons can hit the low 30s°C.
  • June–August: Peak heat. Daytime temperatures in Merzouga routinely exceed 40°C, sometimes 45–48°C. Only recommended for early-morning or evening desert activities.
  • September: Heat begins easing but afternoons are still hot.
  • October–November: Our favourite window — warm, dry, clear skies, and dunes with fewer visitors than the winter peak.
  • December: Mild days, cold nights; a popular month for a "different" Christmas.

Autumn (Oct–Nov): the sweet spot

Autumn combines comfortable daytime temperatures (high 20s°C) with nights that are cool but not bitter. The light is soft, the crowds from European summer holidays have gone, and hotel and camp prices haven't yet hit the December–January peak. If your schedule is flexible, this is when we'd send our own family.

Winter (Dec–Feb): cold nights explained

Winter days in the desert are genuinely pleasant — sunny, dry, often 18–20°C by early afternoon. What catches people out is the night. Because there's no cloud cover and very low humidity, heat radiates straight back out after sunset, and camp temperatures can fall to near freezing between December and February. This is completely manageable with the right layers (see our packing list) and camps provide heavy blankets, but pack as if you're going somewhere cold, not somewhere hot.

Spring (Mar–Apr): the best all-rounder

Spring edges out autumn for many travellers because of what's happening in the landscape: oases are green after winter rains, wildflowers appear in the pre-Sahara, and daytime temperatures are comfortable without yet being hot. April in particular threads the needle between warm days and tolerable nights.

Summer (Jun–Aug): why we don't recommend it

We still run desert tours in summer because some travellers have no other window, but we're upfront about it: midday heat in Merzouga in July and August is genuinely dangerous for anyone not used to it, camel treks are shifted to very early morning or after sunset, and some travellers find the daytime hours in a non-air-conditioned kasbah uncomfortable. If summer is your only option, we'll build the itinerary around the heat rather than pretend it isn't there.

Ramadan and holiday dates

Ramadan shifts roughly 11 days earlier each year, so check the current dates before booking. During Ramadan, daytime restaurant opening hours in smaller towns can be limited (though tourist-facing establishments and desert camps generally still serve travellers normally), and the pace of city life slows until after sunset. It's a fascinating time to visit but worth planning around. Christmas and New Year, plus the Moroccan spring school holidays, are the busiest weeks of the "good" season — book desert camps early if you're travelling then.
