Climate
Egypt is mainly desert. In spite of the Sahara's notorious heat, it can be chilly at night, especially during the winter. As soon as the morning sun appears the sand warms up, but when the sun sets, the desert cools as rapidly as it warmed. The temperature during winter, spring and fall in Egypt is lovely. The summer is pretty hot and sometimes humid in Cairo, more hot but dry heat in Luxor and Aswan. At the Reds Sea is always a lovely temperature.
Below is an indication of the daytime temperatures during the year. The first number is the temperature in Cairo, the second in Aswan.
