If you really want to do some interesting things on a trip to Egypt then first you will have to evaluate what is the best means for you. As per my experience the best time to visit this ancient land is during fall and spring season. Spring lasts from February to April, whereas fall lasts from September to November. Winter months are known to be quite chilly. So if you are not a fan of cold weather then better you should avoid Egypt from December to January.
In case If your main agenda is sight seeing the ancient sites then go in the winter because places like Luxor, Giza, and Saqarra will be cooler. Even in the winter do not ever visit these sites without have a minimum of one bottle of water with you. you will NEED it, extra water is recommended!
