A cactus has a fleshy stem and has no leaves.
Leaves are the parts of any plant which plays a role in transpiration, i.e., leaves transpire. The excess water is therefore lost to the environment from the leaves.
In a cactus, the leaves are modified into thorns. So, there is no such transpiration. There is loss of excess water. Water is therefore retained which can be used by the plant any time. Thus, the extremely hot climate doesn't affect it.
