The climate of Australia

Australia has a mainly arid climate (variants of Köppen climate classification BS and BW) that ranges from semi-desert to desert type of weather. The extreme northeast has a tropical wet and dry climate (Köppen Cfa, Cfc). The southeast corner of the country enjoys an oceanic climate (Köppen Cfb). Summers are hot, while winters are mild due to the far-off location from the poles. Australia lies in the southern hemisphere, in Oceania, and stretches below the Tropic of Capricorn. New Zealand lies to the southeast, the Solomon Islands in the northeast, and Indonesia further away in the north. The low latitudes, proximity to large bodies of water such as Indian and Pacific Oceans, ocean currents, subtropical high-pressure systems, and factors such as El Nino and La Nina influence the climate.

Australia, the largest island and smallest continent in the world, has a diverse landscape with a vast desert in the center, rainforests in the northeast, and mountains in the southeast, east, and southwest. The Great Barrier Reef extends over 1200 miles stretching down from the northeast, while the coastline measures a vast 21,262 miles. Mount Kosciuszko is the highest mountain on the mainland, with a height of 2228 meters. Forests in less arid regions are evergreen with eucalyptus trees, while dry areas mostly grow shrubs, like acacias. The Great Dividing Range lies in the east, with uplands and grasslands running to the coast. Sandstone cliffs and gorges lie in the northwest. Uplands, shrublands, and deserts constitute a large part of central and western Australia.

The average annual rainfall in Australia is a minuscule 406.4mm (16"). The precipitation ranges from less than 254mm (10") in the central zone to more than 1676.4mm (66") in the north. Deserts receive 76.2mm (3") to 254mm (10") of rain, with daily high temperatures often between 32.2°C (90°F) and 40.6°C (105.1°F) in the summer. Summers are hot with daily high temperatures above 26.7°C (80.1°F), while winters are mild in the majority of Australia. Heatwaves are a regular feature as many locations register between 37.8°C (100°F) to 48.9°C (120°F) during peak summer. Westerly winds blow in the southern parts of the country, while sea breezes prevail along the coast. The eastern highlands receive regular snow, as also do Tasmania and the high altitudes of the Great Dividing Range. Frost is common in the southern half during winter nights.

The Northern Territory of Australia sees a tropical wet season from October to April and a dry season from May to September. June average lows dip to 19.4°C (66.9°F), while January average highs register 36.1°C (97°F) in a few places. The Australian Capital Territory has high mountain peaks that see significant snowfall in the winter. The average rainfall is to the tune of 635mm (25"), with the highest percentage of rain during spring and summer. New South Wales registers average temperatures ranging from -7.2°C (19°F) in the alpine zone in July to 32.8°C (91°F) in arid areas in January. Precipitation in the eastern part of the state is between 609.6mm (24") to 1219.2mm (48"). Queensland has hot summers in its western portion, while the southern mountains experience mild to cool temperatures even in the hot season. The central part is hot and dry, with 762mm (30") to 1016mm (40") of annual rainfall.

South Australia is chiefly arid except for the southern coasts that exhibit a Mediterranean type of climate. Rainfall ranges from 152.4mm (6") in Lake Eyre basin to 1193.8mm (47") in the high mountains. Tasmania is mostly temperate with four different seasons. The average sea temperatures during the summer rarely breach the high of 21.1°C (70°F). Victoria ranges from hot in the north to temperate along the coast. The Victorian Alps are cold, with average temperatures below -17.8°C (-0°F) in the winter on the highest peaks. Western Australia is mostly hot and arid, with precipitation in the range of 304.8mm (12") to 1397mm (55"). The cold waters off the western coast keep the area devoid of moisture, resulting in a dry climate in four-fifths of the state.

Oodnadatta recorded the highest ever temperature of 50.6°C (123.1°F) on January 2, 1960, in Australia. Charlotte Pass in the Snowy Mountains recorded the coldest temperature of -30.6°C (-23.1°F) on June 29, 1994, in Australia.

The best time to visit Australia

The best time to visit Australia is during the mild winter season, which occurs from June to August in the southern hemisphere. The weather is cool and refreshing compared to the hot and dry summer. Winter also allows tourists to enjoy adventures in the Great Australian Outback, the vast desert in the core of the country. The probability of cyclones is low, but it is rainy in Western Australia, and the cold south needs winter wear. Spring and autumn are pleasant for a visit to the southern part of the country, where the climate is of the Mediterranean type.

The worst time to visit Australia

The worst time to visit Australia is during the scorching summer from December to February. The heat is oppressive, particularly in the western and central areas, and there are prolonged periods of hot weather. Summer weather is usually harsh for traveling in the majority of the country. Additionally, the interior of the country faces droughts and scarcity of water. The mountain regions in the south are an exception, where tourists enjoy temperate weather even in the hot season. For an extended trip to Australia, it is better to avoid the period of blistering heat.

Weather hazards

Australia is prone to severe droughts, heatwaves, bushfires, and dust storms. Occasional tornadoes, tropical cyclones, and frosts pose threats to the population. Heatwaves are frequent during the summer in many parts of the country. Dust storms are frequent in the arid regions. The hot and dry climate feeds bushfires that consume the dry vegetation as high-speed winds spread them over large areas.
Flooding is common in the extreme north, where rainfall is high. A large part, in the heart of the country, struggles with less rain, and frequent droughts. Cyclones average five to six times, mostly near the coast, with wind speeds over 321.9km/h (200mph) that inflict substantial damages on infrastructure and crops. Blizzards occasionally occur in the high mountains of Victoria and New South Wales.
