Heading south from Luxor, the fertile green Nile Valley narrows considerably and becomes more and more enclosed by the desert, which in some places edges dramatically close to the river banks. The climate also changes and becomes increasingly desertlike, with mostly warm and dry days in winter – there’s an average temperature of about 26°C during the day – but often surprisingly cold at night.
