More accurate to say poor weather is not the time to do it. I have done it in May with friends on a beautiful sunny settled May day. Warm in Fort William, complete snow cover on the plateau, but perfectly ok to walk on with standard walking boots. I had fluked a week of decent weather, it only deteriorated the day before I went home.
