What is the weather like in the Sahara by season?

The defining feature of the Moroccan Sahara — around Merzouga's Erg Chebbi and Zagora's Erg Chigaga — is its extreme daily temperature swing. Because dry desert air holds almost no heat, the difference between a scorching afternoon and a cold night can exceed 20°C in a single day, in every season. Whenever you visit, you pack for two climates at once: sun protection for the day, warm layers for after dark.

Spring (March to May) is one of the two best windows. March and April bring warm, comfortable days (mid-20s to low-30s°C) and mild, pleasant nights — ideal for camel treks, dune walks and sleeping out under the stars. By late May the midday heat climbs sharply, so activities shift to early morning and late afternoon, but the evenings stay beautifully warm. Skies are clear and the light is superb.

Summer (June to August) is the Sahara at its most punishing. Daytime temperatures routinely exceed 45°C, and the open dunes at midday are genuinely dangerous, not romantic. We only run summer desert trips strictly around sunrise and sunset, with shaded, ventilated luxury camps and serious hydration — never daytime exposure. Nights, by contrast, are warm and comfortable. For most travellers, summer is the month to save the desert for another season.

Autumn (September to November) is the other prime window, mirroring spring in reverse. Early September is still hot, but by late September through October the desert is perfect — warm days, mild nights, dust-free skies and the clearest stargazing of the year. November stays comfortable by day but the nights cool quickly toward winter, so a warm jacket becomes essential after sunset.

Winter (December to February) has lovely, sunny days in the high-teens to low-20s°C, but the nights are genuinely cold — frequently near or below freezing, with biting wind. A winter desert night is unforgettable for its clear skies and cosy, heated camps, but it demands proper cold-weather gear and a camp built for winter (heating, thick blankets, hot water bottles). Rain is rare across all seasons, though brief downpours and flash floods can occur, mainly in autumn and spring.
