Sahara (Merzouga) in October

October through April is your window. December and January nights drop to near freezing while days hit 20°C — perfect for hiking the dunes. March and April bring wildflowers after rare rains. Avoid May through September unless you enjoy 45°C temperatures that make walking on sand impossible. The full moon illuminates the entire desert in silver light, making night photography spectacular. Ramadan affects restaurant hours and desert camp meal times, so check dates before booking.
