First, let's talk about the weather. The average high temperature in Marrakech during February is 21ºC, which means it's warm during the day but can get chilly at night. So, you'll need to bring some warm clothes, including a winter jacket, for the desert experience.
During the day, it's hot, so it's best to pack lightweight, loose-fitting clothes in natural fabrics such as linen, silk, cotton, and bamboo that will keep you cool and are easy to wash and dry. If you're planning a trip to the desert, be sure to take along a scarf or sarong to tie around your face to keep out the blowing sand. You should also wear a long-sleeved shirt and full-length trousers to protect yourself from mosquitoes.
