It's more that every substance has a specific heat capacity. That is, how much energy it takes to raise 1 g of that substance one degree Celsius.

Water happens to have some of the highest specific heat capacities. Therefore, the south can "store" more energy in the hot months, and release that same energy in the cool months better than the north can

Thank god we have these big wet heat sinks available to help keep climate stable.
