Cairo experiences a hot desert climate with scorching summers and mild winters, making it one of the driest major cities on Earth.
Rainfall is so minimal—averaging less than 25mm annually—that waterproof clothing is essentially unnecessary year-round.
Summer temperatures routinely exceed 35°C and can reach 40°C, while winter days hover around a pleasant 18-20°C with cooler evenings dipping to 9°C.
Low humidity prevails throughout the year, though the khamsin—hot, sandy spring winds—can make conditions feel harsh and warrant eye protection.
Light-colored, loose-fitting fabrics that cover skin provide the best defense against both intense sun and the conservative dress expectations of many neighborhoods.
