Basically, the Sun rises in the East, and sets in the West, so you would be walking towards the West. But, the arc is longer in Summer, so the Sun may rise in the North-east, pass to the South at noon, and set in the North-west, so the Sun takes longer to rise and set. It is during the shorter days of Winter that the Sun makes the shortest arc of South-east to South-west as viewed in the Northern Hemisphere.
