I recommend only partial watering, just a splash or shower of water in the evening for a bit of cooling. Then in the fall when it cools down many kinds will have another period of activity and a few good soaks of water can be given. During the winter most cacti like to be cool to cold and dry with plenty of fresh air. If kept cold enough they will need very little water for several months. A good winter dormancy helps make flowers the following season.
Succulents are much more complicated.
You have to learn the winter growers from the spring to summer growers. The winter growers like very frequent light watering during their growth season as many come from regions of frequent nightly fogs and drizzles. I try to mark in the catalog those that are winter growers. Remember the winter growers like to grow when it is cool with short days. The winter growers have no idea that the earth has another hemisphere, they have no idea what goes on elsewhere.
