Weather in Australia
Australia experiences temperate weather for most of the year but
the climate can vary due to the size of our continent. The northern
states typically experience warm weather much of the time, with the
southern states experiencing cooler winters. Australia is also one of
the driest continents on earth with an average annual rainfall of less
than 600 millimetres. Like all countries in the southern hemisphere,
Australia's seasons are opposite to those in the northern hemisphere.
December to February is summer; March to May is autumn; June to August
is winter; and September to November is spring.
New South Wales lies in the temperate zone. The Great Dividing
Range, in the east of the state, has a large impact on the climate,
creating four distinct zones: the coastal strip, the highlands, the
Western Slopes and the flatter country to the west. Sydney’s climate is
pleasantly temperate all year round with more than 340 sunny days a
year. In summer (December to February), average maximum temperatures in
Sydney are around 26°C. It can also be humid at this time with an
average humidity of 65 per cent. Average maximum temperatures in the
winter (June-August) are around 16°C. Sydney’s rainfall is highest
between March and June.
Victoria’s climate is marked by a range of different climate
zones, from the hot, dry regions of the northwest to the alpine
snowfields in the northeast. Average annual rainfall ranges from less
than 250 millimetres in parts to in excess of 1800 millimetres over some
of the mountainous regions. Melbourne has a reputation for its
changeable weather, but as a general rule, the city enjoys a temperate
climate with warm to hot summers; mild, balmy springs and autumns; and
cool winters. Temperatures average 25°C in summer and 14°C in winter.
Rainfall is highest from May to October.
South Australia’s climate varies from hot and dry in the
interior to milder, wetter climates in the south and on the south-east
coast. Adelaide generally has mild, wet winters and hot, dry summers. It
is the driest of all the Australian capital cities. The average
rainfall in January and February (summer) is around 20 millimetres, but
months with no rain are common. June is the wettest month of the year,
averaging around 80 millimetres. The average maximum temperature is 29°C
in summer and 15–16°C in winter.
Western Australia has a number of climatic zones due to its
enormous size. In the north-west, heavy rains mark the summer 'wet'
season, although the interior is mostly dry with high summer
temperatures; while the southwest has mild, wet winters and hot, dry
summers. Perth’s rainfall is highest between May and September. February
is usually the hottest month of the year, averaging temperatures of
31°C. A sea breeze called ‘The Fremantle Doctor’, blows from the
south-west providing relief from the heat. Winters are relatively cool
and wet with temperatures of around 18°C.
Brisbane has a subtropical climate with warm or hot weather for
most of the year. In summer (December – February), maximum temperatures
average around 30°C. The city experiences most rainfall in summer which
can sometimes take the form of thunderstorms with torrential rain. It
can be very humid during this time.
Winter is generally dry, mild and pleasant. Most winter days are sunny with average temperatures of around 17°C. Average monthly rainfall over the year is around 96 millimetres.

Queensland’s climate is characterised by low rainfall and hot
summers in the inland west, a monsoon season in the north, and warm
temperate conditions along the coastal strip. The dry inland plains
record the hottest temperatures during summer, when the annual median
rainfall is below 200 millimetres. Cairns enjoys a tropical climate,
with hot and humid summers and mild, dry winters. The average annual
rainfall is 1992 millimetres, mostly falling between January and March.
Typical daytime temperatures in Cairns are 23-31°C in mid-summer and
18°C in mid-winter. Tropical cyclones sometimes occur from November
through May in coastal regions.
Since Tasmania is an island with no place more than 115
kilometres from the sea, its climate is classified as mild temperate
maritime. Summers are mild and rainfall is spread fairly evenly
throughout the year, although the winter months are the wettest. Because
of its latitude, the seasons are much more evident in Tasmania than the
rest of Australia. Hobart has four distinct seasons. The warmest
months, January and February, are also the driest with average
temperatures of around 21°C. While exposed to the southerly winds from
the Antarctic, Hobart is protected by Mt Wellington from the worst
weather.
Canberra has a mostly dry, continental climate with warm to hot
summers and cool winters. The average annual rainfall is 629 millimetres
which is fairly evenly distributed throughout the year. The wettest
month is October and the driest is June. During winter, snow falls in
the nearby Australian Alps. January is the hottest month with average
maximum temperatures of 28°C. The coldest month is July with average
daily temperatures of 11°C which can drop below zero at night. Canberra
has around nine hours a day of sunshine in summer, dropping to around
five hours in winter.
The Northern Territory's climate is distinctly different from
that of southern Australia, and varies greatly between the northern
part, known as the 'Top End' and the southern extremities. There are two
distinct seasons: the 'wet' (October to April) and the 'dry' (May to
September). Alice Springs’ climate is one of extremes with hot summers
and cold winters when night time temperatures can fall below zero.
Rainfall varies dramatically from year to year, but the annual average
is around 286 millimetres. Daytime summer temperatures are generally in
the high 30s, with dry, cool nights. Spring can bring thunderstorms,
hail and dust storms.
Broome has a tropical climate with hot and humid summers and
warm winters and two distinct seasons: ‘wet’ (December to March) and
‘dry’ (the rest of the year). From October to April temperatures reach
around 33°C. Winters (June-August) are mild, with average July
temperatures around 27°C during the day. Overnight temperatures rarely
fall below 5°C or much higher in the summer. The average annual rainfall
is 532 millimetres but sometimes no rain falls for months on end.
January to March is the wettest time of year. Tropical cyclones can
occur from November to April, most commonly in January and February.
Darwin in the Top End of the Northern Territory has two distinct
seasons, the 'wet' and the 'dry'. The wet season runs from November
until April, and is characterised by high humidity, monsoonal rains and
storms. Temperatures typically range from a minimum of 25°C to a maximum
of 33°C. The 'dry’ season, from May until October, is characterised by
warm, dry sunny days and cool nights. Temperatures typically range from
21°C to 32°C, and humidity levels are much lower. Here you will find
information on temperature, rainfall and seasonal activities to help you
plan your holiday in Darwin.
