Since the Nile is the longest river in the world, the weather changes remarkably all along it. Close to the equator it is hot and the vegetation equatorial and thick, due to heavy summer rain.
In the north where it flows through the deserts it has been damed of in places to flood the fields in Egypt where there is little or no rain. However it is safe to say that all along it's the weather reaches 40 degrees C in summer, and winters are generally mild. Although the temperature change between night and day can be quite severe, and can feel very cold for the unprepared. Winds can also sweep down from the mountain ranges in the extreme North of Africa.
The vegetation is the best indicator of the the weather, where there is high rainfall, and intense heat, tropical forests, or reed beds and swamps exist, with the mosquitos who inhabit them. The burning heat of the desert is much less humid yet dangeous to travelers, for the lack of water in the intense heat and sand storms.
