Average Temperatures to expect for your time in Egypt.
Always good to know.
Cairo, the capital, is located about 180 kilometers (110 miles) away from the sea, but it's at the edge of the huge Nile River Delta, so its climate is halfway between the Mediterranean and the desert climate: the summer temperatures are lower than in the desert area but higher than on the coast; highs are around 35 °C (95 °F) in July and August, but moisture is quite high, so the heat can be stifling. Summer is long: the maximum temperatures exceed 30 °C (86 °F) from May to mid-October. Within the city, the unpleasant sensation of heat is increased by the so-called "urban heat island effect" which occurs in big cities, and also by pollution.
In the interior, the climate is desert, with virtually no rain; the temperatures increase gradually as you head south. The diurnal temperature range is remarkable because of both clear skies and low humidity. Winters are mild and sunny, but nights are cool to cold, ranging from 5/7 °C (41/45 °F) in the central area (see Luxor) to 10/11 °C in the southern area (see Aswan), though the temperature in the coldest nights can approach freezing (0 °C or 32 °F). The winter days are pleasantly mild or warm, about 20/22 °C (68/72 °F) on average. In inland areas, summers are scorching hot, with highs ranging from 36/37 °C (97/99 °F) in the center-north to 40/42 °C (104/108 °F) in the south, and during this season, the sun hits hard. In the hottest days, the temperature in the south can reach as high as 50/52 °C (122/126 °F).
Luxor

On the Mediterranean coast (see Alexandria, Marsa Matrouh), there's a very mild, spring-like winter: highs are around 18/19 °C (64/66 °F) and lows around 9/10 °C (48/50 °F), though this is the only period of the year when weak or moderate rains occur. Summer is long, muggy and sunny, with highs around 30 °C (86 °F), but tempered by sea breezes. The humidity is high especially in the delta of the Nile River.
