Introduction
Australia, a huge country of more than 7.5 million square kilometers (3 million square miles), crossed by the Tropic of Capricorn, has largely an
arid climate, classified as desert or semi-desert, except in the extreme north, where it is
tropical (with a rainy and a dry season), and on the southern coasts, where it is more
temperate, oceanic or Mediterranean.
In summer, coastal cities can be affected by
heat waves caused by torrid winds from the desert, sometimes accompanied by sand.
On the other hand, although the winter is mild, the south, where almost all the main cities are located, can be affected by
cold winds of Antarctic origin, and since some houses have no heating or are poorly insulated, the feeling of cold can be greater than you might expect.
Being in the Southern Hemisphere, Australia has, of course, reversed seasons in comparison with Europe or North America.
Arid climate
Outback
In the vast area generically called "
Outback", the climate is arid: it is considered desert where precipitation drops below 200 mm (8 in) per year (see the area inside the burgundy line) and semi-desert in the area where annual precipitation is between 200 and 400 millimeters (8 and 16 inches) per year (the area within the blue line).
In Australia, there are several
deserts, such as the Great Sandy Desert, the Gibson Desert, the Great Victoria Desert, and the Simpson Desert. In this area, there are no large cities and population density is low.
In the semi-desert area (between the burgundy and the blue lines), the
rains fall in the form of downpours or thunderstorms in the hottest period, at least in the north-central part, while in the southernmost part they occur mostly in winter. In the most arid area, rain is very rare and sporadic, however, every now and then a thunderstorm may erupt, most likely in summer.
Temperatures vary depending on areas: winter is milder in the northern part, while summer is hot almost everywhere, except in the southernmost part and in the short western coastal stretch.
Port Hedland
On the north-west coast of Western Australia (see Eighty Mile Beach), the heat is intense even along the coast. For example, in
Port Hedland, the average daily temperature in January, the hottest month, is 31 °C (88 °F).
At night, the temperature can drop below 10 °C (50 °F) from May to September. The coldest record is 4 °C (39.2 °F) and was set in July 2006.
During the day, the temperature can exceed 40 °C (104 °F) from September to April, and the highest record is 49 °C (120.2 °F), set in January 2008.
Here are the average temperatures in Port Hedland.

The Eighty Mile Beach is located north-east of Port Hedland, therefore the sea is slightly warmer in winter. Here the heat is intense from October to April.
In
Oodnadatta, in the state of South Australia, the average maximum temperature exceeds 35 °C (95 °F) from December to February. However, the temperature can sometimes exceed 40 °C (104 °F) from September to April, with records of 48 °C (118 °F) in December and January. The climate is milder from May to August, when daytime temperatures are around 20 °C (68 °F) and nights can be cool or even cold (the cold records are around freezing from June to August). Here, only 180 mm (7 in) of rain fall per year.
Further north, the hot period is longer, so much so that highs normally exceed 35 °C (95 °F) from October to March at the Tropic of Capricorn. Some cities are located a few hundred meters (more than one thousand feet) above sea level and are therefore slightly cooler.
Alice Springs
Alice Springs is located in the state of the Northern Territory, just south of the Tropic of Capricorn and practically at the center of Australia. We are in the area of the MacDonnell Ranges and at 500 meters (1,650 feet) above sea level. The city is still hot in summer, though the highest recorded temperature is "only" 45 °C (113 °F). In winter, it can get fairly cold due to the altitude, and at night the temperature can drop to a few degrees below freezing, but during the day, with the sun shining, the temperature rises a lot and the air becomes pleasantly mild. Here are the average temperatures.

Mediterranean climate
In the two southern areas indicated on the map, the climate is Mediterranean, with mild, rainy winters and warm, sunny summers. Their proximity to the ocean makes the summer windy, on the other hand, since they are relatively close to the desert, sometimes heat waves can occur, with highs around 40 °C (104 °F).
Perth
In
Perth, Western Australia, the daily average temperature ranges from 13.5 °C (56.5 °F) in July to 25 °C (77 °F) in January and February. In a typical year, 700 mm (27.5 in) of rain fall, most of which occur from May to August, with a maximum of 140 mm (5.5 in) in July, the central month of winter. The temperature never drops below freezing, although in the metropolitan area there may be slight frosts at night in the winter months. From November to March, the hot wind from the desert can raise the temperature to around 40 °C (104 °F) for a few days, with peaks of 45 °C (113 °F), but highs are normally around 30/32 °C (86/90 °F) and lively sea breezes blow from the ocean in the afternoon. Here are the average temperatures.

South of Perth, in the south-western tip of Australia, in towns such as Denmark and Pemberton, the rains reach 1,000/1,200 mm (39/47 in) per year, but still with a Mediterranean pattern (ie with rainy winters and dry summers); summers are a bit cooler, but short waves of intense heat are possible here as well.
Adelaide
In
Adelaide, South Australia, the climate is similar to that of Perth, although summer is slightly cooler and winter less rainy. The average temperature ranges from 22.7 °C (74 °F) in February to 11.3 °C (52.3 °F) in July. Here, too, the heat of the summer days is cooled by sea breezes, and also, from November to March, short heat waves are possible, with peaks around 40 °C (104 °F). Here are the average temperatures.

Tropical climate
The vast northern area of Australia has a
tropical climate, with a dry, sunny season ("the dry", usually from May to October) and a rainy and muggy season ("the wet", usually from November to April). Annual rainfall exceeds 400 mm (15.5 in), and it's more abundant along the northernmost and the eastern coasts, where it exceeds 1,200 mm (47 in). The tropical rains mainly occur in the form of downpours or thunderstorms in the afternoon or evening.
In the south-eastern part, where Brisbane is located, winter is cooler, so the climate is sub-tropical instead of tropical. In the driest areas, we find savanna-type vegetation, while in the wettest areas of the north-eastern coast we find rainforests.
In the
far north, in Arnhem Land and the Cape York Peninsula, the weather is hot and summer-like all year round, while the more you go to the south, the greater the difference is between the seasons.
Darwin
In
Darwin, the capital of the Northern Territory, 1,830 millimeters (72 inches) of rain fall per year, the majority of which occur from November to early April. The rainiest month is January, with 470 mm (18.5 in) of rain. On the contrary, from May to September it almost never rains. Here is the average precipitation.

Cairns
Along the north-eastern coast, in cities like
Cairns (Queensland), the rains are abundant, in fact, almost 2,000 mm (80 in) of rain fall annually, including more than 100 mm (4 in) from December to April. In any case, the sun shines quite often throughout the year, since the rains, however intense, generally do not last long. Here is the average precipitation.

Between Cairns and Innisfail, Mount Bellenden Ker is rain-soaked, so much so that at the top, at 1,593 meters (5,226 feet) above sea level, up to 8 meters (315 inches or 26.2 feet) of rain fall every year!
Innisfail is the rainiest city in Australia, and it's the only city in the Australian tropical zone not to have a dry season. In fact, even in winter and spring some showers may occur: on average, 3,500 mm (138 in) of rain fall per year, with a maximum of as high as 600 mm (23.5 in) in March and a minimum of 80 mm (3.1 in) in September.
At some distance from the east coast of Queensland, in the Coral Sea (belonging to the Pacific Ocean) we find the
Great Barrier Reef, the world's largest coral reef, up to 2,300 km (1,400 miles) long.
Brisbane
Proceeding towards the south-east along the coast, the temperature gradually decreases, so the climate is more enjoyable. In
Brisbane, the capital of Queensland, the summer, from November to March, is hot and moist, with some chance of thunderstorms; however, the sun often shines. Winter, from June to August, is very mild, with many sunny days, sometimes, however it can get cold at night, to the point that the temperature can approach freezing.
The average rainfall is 1,000 mm (40 in) per year, with a maximum in summer. Every now and then, there is some risk of heavy rainfall in almost all the months of the year, except maybe in August and September. In Brisbane, waves of scorching heat from the desert are rarer than in other cities of Australia, but they are still possible from October to March. Here are the average temperatures.

South-east
In the south-east, in the states of New South Wales and Victoria, there is a
temperate climate, with rainfall generally not abundant, but well distributed over the seasons. The weather is cooler in Tasmania and along the southernmost coast, as well as in the hilly and mountainous regions of the extreme south-east.
Canberra
Canberra, the Australian Capital, is located at 600 meters (2,000 feet) above sea level, and because of the altitude it has a cool climate, in fact the average temperature ranges from 21.5 °C (70.5 °F) in January to 6 °C (43 °F) in July. Summer is therefore not so warm, while winter is quite cold, at least by Australian standards, and sometimes it can be foggy.
In winter, frosts and even some light snowfalls are possible, but sometimes it can be a bit cold at night even in summer.
During summer, from November to February, there can be heatwaves here as well, during which the temperatures can rise to around 40 °C (104 °F). Here are the average temperatures.

Sydney
Sydney, lying on the coast, is much
milder, especially in winter: here, the average temperature ranges from 24 °C (75 °F) in January to 13 °C (55.5 °F) in July. Rainfall is fairly abundant, since it amounts to 1,000 millimeters (40 in) per year, and it is well distributed over the seasons, even though the rainiest season is autumn. In summer, the rains can occur in the form of downpours or thunderstorms.
Waves of scorching heat are not so rare, and are possible from November to March, often accompanied by strong gusts of dry wind that can spread fires in the hills surrounding the city.

Melbourne
Melbourne is located further south, in the state of Victoria, and overlooks a bay (Port Phillip Bay) which opens into the strait that separates Australia from Tasmania (Bass Strait). The climate is quite
cool, windy and unstable. The average temperature ranges from 20.5 °C (68.5 °F) in January and February to 10 °C (49 °F) in July.
Here too, sometimes there may be heat waves (which are more intense from November to March), though usually short-lived. Summer is usually pleasantly warm, in fact, the Australian Open tennis tournament is held in January, but there'a rule called Heat Policy, whereby matches are suspended with extremely high temperatures. In summer, the sun frequently shines (though not always), while from May to August there are 4/5 hours of sunshine per day. The rains are not abundant, reaching only 600 mm (23.5 in) per year, but they are well distributed, with a relative minimum in summer.

The sea temperature in Melbourne is significantly lower than in Sydney, it's also a bit lower than in Adelaide, and remains quite cool even in the summer months.
Australian Alps
In south-eastern Australia, between Melbourne and Canberra, there is a mountain range, called
Australian Alps; the highest mountain in the chain and across Australia is Mount Kosciuszko, which reaches 2,228 meters (7,310 feet). This area is humid and rainy, cold in winter, even snowy above 1,500 meters (5,000 feet), and cool in summer.
There are also resorts equipped for winter sports.
Here are the average temperatures of Thredbo, located at 1,400 meters (4,600 feet) above sea level.

Tasmania
Further south we find
Tasmania, the southernmost island, which, being exposed to the westerly winds, has a
mild oceanic climate. However, every now and then, during winter, a cold air mass can reach the island, and snowfall can occur in inland hills and mountains. On the other hand, in summer, even Tasmania can sometimes be reached by the hot wind from the desert, although by the time this wind reaches Tasmania, it is generally weakened.
Rainfall is more abundant in the wester part, where it exceeds 1,200 mm (47 in) per year.
The capital,
Hobart, is located in the eastern part and receives only 565 mm (22.2 in) of rain, which, however, is well distributed throughout the year, and occurs in the form of frequent showers or drizzles. The average temperature ranges from 8.5 °C (47.5 °F) in July to 17.5 °C (63.5 °F) in January and February. Here are the average temperatures.

The temperature of the sea in Tasmania is cold all year round, and it reaches at most 17 °C (63 °F) in February and March in the southern part (see Hobart) and 18 °C (64 °F) in the north.
Cyclones
Australia can be affected by
tropical cyclones, intense low-pressure areas that are formed when the sea is very warm, and is therefore able to provide enough energy. Cyclones bring strong winds and torrential rains and affect mainly the northern coasts, although sometimes they can penetrate the interior (especially in Western Australia), weakening along the way but still bringing heavy rains.
Cyclones are generally formed between mid-November and mid-May, but the phenomenon is more likely from January to mid-April.
In the following image, we can see the areas that have been affected by cyclones in the period 1950-2005 (the points refer to the eye of the cyclone, so the affected area is larger).
El Niño and La Niña
Australia's climate is also affected by the phenomenon known as
El Niño, which is associated with
drought more or less severe throughout the country, particularly along the north and east coast, where it reduces the summer rains, and in the south, where droughts are accompanied by
hot winds from the desert, which can cause fires.
The opposite phenomenon,
La Niña, brings
rainfall more abundant than usual in the north and east, especially in spring and summer, and also an increase in the number of cyclones.
