New South Wales climate overview

New South Wales occupies a large part of the southeast of the Australian continent, with borders stretching inland over half way to the interior. The main population centres are on or near the east coast, most famously around Sydney with its Harbour Bridge and spectacular Opera House.

The eastern third of New South Wales has a subtropical climate with rainfall in all months, while further west rainfall levels are lower and a relatively dry period occurs during the summer. The border between these two regions is roughly the western extent of the Great Dividing Range, a broad mountain chain that runs parallel to the coast about 100 miles inland, locally known as the 'Tablelands'.

Along the entire length of the New South Wales coast long stretches of golden beaches with impressive surf can be found where summer temperatures are generally comfortable to warm. In winter the coast also has the mildest weather with rare frosts. However Sydney and regions to the north can suffer torrential rain and occasional damage from large hailstones particularly in late spring and early summer.

Inland summers are hotter and winters colder. On the Tablelands, eastern regions receive more rain than those to the west, and there is more rainfall in the south of the State, much of which falls as snow at higher elevations in winter. It is here in the Snowy Mountains that Australia's highest peaks are found.

Some of Australia's richest farming land is located on the Tablelands and the plains to the west where sheep and cattle gradually give way to wheat and other cereal crops. The country's longest river system, the Murray-Darling, runs through the interior of the state and along the border with Victoria where it feeds irrigated fruit and wine regions in the south.

To the west of the Darling River are large semi-arid regions with widely dispersed sheep and cattle stations and the remote mining town of Broken Hill.
