The Australian climate varies a lot depending on which state you are going to visit. The question "What's the weather like at my Australian holiday destination?" is important, right?
Although Australians always hope for rain in drought conditions, they will certainly understand that you don't want rain when you are out there :).
That's why I have researched information about the Australian weather and general climate facts for you.
Because Australia is such a big country, there will be always a region with pleasant weather at any time of the year.
However, I have to add a warning! Even in a mostly dry and sunny country like Australia, the weather is not 100% predictable.
Let me give you an example. My husband wanted to celebrate a special birthday of his in Adelaide with family and friends. His birthday is in late November which is spring in South Australia, so we expected at least mild weather. A barbecue was planned, lo and behold, this certain day had a maximum of 15°C, and a rather cold evening with 10°C.
The following year we were told that Adelaide had lovely 30°C on that day.
So, while climate charts and reports give you average weather conditions, collected over a long period of time, the actual weather can still be different on a certain day.
This sequence of seasons is valid for all countries in the southern hemisphere.
With Australia's vast dimensions, you can imagine that it is hard to pick a season that has ideal weather in each and every corner of the country. It often depends on the activities you're planning for your holiday trip.
One fact is for certain, Australia's weather is much dryer than in any other country of the world. Rainfall is rather unpredictable in most parts of the continent, except for the northern regions which are under influence of the tropical monsoons.
The central and southern parts of Western Australia, the southern Northern Territory, the central and northern parts of South Australia, as well as the far west of Queensland New South Wales belong to Australia's dry and desert regions.
This map certainly gives you a better overview of the climate zones in Australia than my descriptions.
Anyway, the central parts of Australia have hot summers with temperatures of 40°C and more during the day, while the average day time temps in winter are around 20°C. At night temperatures vary from 20°C in summer to freezing zero in winter. Clear blue skies and low humidity make the hot days tolerable.
The arid and semi-arid areas of inland Australia receive between 100 and 300 mm rain per year, but this is rather unpredictable. The northern parts get perhaps a little more rain, depending how far south the monsoon clouds make their way. All in all, you'll never know when the rain comes in these driest parts of Australia.
Regions north of the Tropic of Capricorn are known as the tropics. Towns along the tropic are Rockhampton on the Queensland coast and Alice Springs in central Australia. On the Western Australian coast the marker is half way between Carnavon and Exmouth.
The weather in Australia's tropics has two different seasons, the dry and the wet. The dry season is from May to October in the Australian winter months. However, winter in the tropics is not as cold as in the southern states. Average temperatures during the day are in the low 20s, but the nights can be rather cold.b
At the end of the dry season humidity builds up, it is getting hot and sticky. It can take a few weeks until the first rain and thunderstorms open the wet season.
It doesn't rain all day long during the wet, but the rainfall is usually heavy and causes flooding. The wet is also the time when cyclones occur along Australia's northern coastlines.
However, when the parched land finally gets some rain, it is amazing to see the wildflowers emerge from the red sand. That's just awesome.
Australia's temperate regions are in the south and south eastern parts of the continent. They include Tasmania and the coastal areas of New South Wales, Victoria and South Australia. The weather in the temperate regions has distinctive seasons.
Summers are warm with average temperatures around 30°C, and sometimes they have heat waves that can last for weeks.
Winters are not as cold as in most European countries. Apart from the mountainous areas of the southern Great Dividing Range, you'll hardly ever see snow in the temperate regions. The snowfields in New South Wales and Victoria receive regular snow in winter, and they are considered bigger than those in Switzerland.
The weather in the temperate regions is rather changeable. A southerly change with cold winds on the coastlines can make you shiver even in summer.
Please be very careful with any open fire, even your cigarettes on days of high fire danger. During the summer months most states have fire bans, that means you are not allowed to use you camping stove outside, let alone have a camp fire going. You'll get information about the state of fire danger from local newspapers and in the news. You'll also see these warning signs along the main highways. Please obey these rules, and don't be the fool who causes a bush fire.
There's a long history of severe bush fires in Australia. When the fires get out of control and threaten the capital cities, you'll certainly get to see the news around the world. In February 1983 more than 100 bush fires damaged more than one million hectares of bushland in South Australia and Victoria. 76 people died in the fires. This series of fires are known as the "Ash Wednesday", a sad event caused by the severe Australian climate conditions.
