The best time to visit Luxor, Egypt, is from October to April when the weather is cooler and more comfortable, with daytime temperatures ranging from 20°C to 30°C (68°F to 86°F). This period is ideal for exploring Luxor's iconic sites such as the Valley of the Kings, Karnak Temple, and Luxor Temple, without the discomfort of extreme heat. During these months, you can also enjoy cultural events and festivals, and although it's peak tourist season, the mild weather makes sightseeing much more pleasant. However, if you don't mind high temperatures and prefer fewer crowds, visiting during the summer months can also be an option, provided you take precautions to stay hydrated and cool.
