Heat is stored in masses. How much heat depends on the temperature change, and the heat capacity. Things like water have very high heat capacity, so that if solar energy impinges, the temperature of the water does not change much. On the other hand, sand, and air, do not have high heat capacity, so their temperature fluctuates greatly if energy impinges on them.
