Do you need to know, when is the best time to go to New South Wales? Then you should take a look here, what weather you can expect there during the year.
New South Wales is part of Australia. The climate of Australia varies widely, as the country is very large. The largest part of Australia is arid to semiarid, temperate in south and east, tropical in north. The northern part of Australia has a tropical climate with tropical rainforests, grasslands and deserts. Winter in Australia is usually mild, there are not so huge contrasts between summer and winter temperatures as on the northern hemisphere. But on some places the temperatures can go down below zero in winter.
