It sounds like it's about ready: I recommend repotting when the plant is about three times the width of the pot, since they like to be a little crowded. As for the season, we do it in the fall, because they grow actively in the winter, here. If it grows more in the summer, there, the spring is the time to do it.
Just bump it up another 5 cm or so in pot size, and use a pot that is wider than it is tall. We have commercial "Cactus Mix" to use as a potting compost, here. If that isn't available, there, sift the fine bits out of a regular potting compost, and replace them with horticultural grit and perlite.
