A very simple solitary ritual by Kate West, found in The Real Witch's Handbook.
The main themes of this festival are the rebirth of the Sun, the start of the days of increasing light and the rise of the Oak King.
The simplest way to celebrate Yule is to rise before dawn to greet the rising Sun. Many diaries and almanacs will give the time of the rising and setting of the Sun, and for that matter, the Moon. If you live near the sea, tide-tables will perform the same function. If it is possible, go out, preferably to a high place, to watch the Sun rise. Alternatively, choose a window facing the direction of Sunrise. As before, call upon the elements, the Goddess and God to be with you. As the Sun rises above the horizon, give thanks for the return of the light and warmth that it brings.
This is the very beginning of the return of new life to the land, the spark of light which brings promise with it. As a time beginnings it is also a time to reflect upon any new starts you may wish to make and perhaps dedicate them to the returning Sun. If you are outside, look around you for a stone, pebble or twig – you are sure to see something which catches your eye – and take this as a reminder of the promise you have decided to make.
