Is Melbourne hot in summer?

Most families here have no air conditioning. This summer is really hot! It's more than 44+ for several days in a row, and it's 1 1 at night, so I dare not take a holiday. . . But summer in Melbourne lasts only a few days, and then it gets cold. . . Those were hard days.

Ps: If the house you rent is good, it should be air-conditioned. But the electricity bill will be settled by yourself!
