Egypt Visiting

Peak tourist season in Egypt runs from mid October to May, during winter and spring. From May until October, the temperatures are fairly high, especially in Luxor and the southern parts of the country.

Egypt is one of the hottest and sunniest countries in the world. With the exception of a strip along the Mediterranean coast, Egypt has a desert climate, being entirely within the Sahara. The Mediterranean coastal strip has an average annual rainfall of 100–200 mm. In central and southern Egypt several years may pass without any significant rain.

Winters are generally warm in the south of Egypt, but temperatures fall rather abruptly at night so that desert evenings in winter can be quite chilly. The heat of southern Egypt in summer is fierce, and there is almost no relief from one day to another. The very low humidity, however, makes the heat more bearable.
