The country's climate ranges from Mediterranean on the Mediterranean coast and in the Nile Delta to desert-like in Cairo, Middle and Upper Egypt. The best time to visit Egypt as a whole is from mid-March to mid-May and from mid-September to mid-November. This excludes the very hot and dry summer months and the somewhat cooler winter months, when temperatures are lower, especially at night. In spring, from March to June, a hot sand and dust wind, the Chamsin, often blows through the country from the south.
