The Australian spring starts on September 1 and ends on November 30, which heralds the arrival of summer. The seasons are the opposite from places in the Northern Hemisphere like in North America and Europe.
Spring has generally fine weather although late in the season you may get cyclones, wind, and rain to parts of the northern regions of Queensland, Western Australia, and the Northern Territory. The northern wet season begins around late October.
Australia occupies such a large geographical area that parts of it lie north and south of the Tropic of Capricorn. Spring in Australia happens some three months before the summer solstice, in the month of the spring equinox.
Spring is a time of warming temperatures just before the summer heat hits the continent. You will find warmer weather in areas of northern and western Australia, the Northern Territory from Darwin south to the Tanami Desert, most of coastal Queensland and the Great Barrier Reef. The weather gets progressively cooler as you travel south. For example, at the top end of Australia in the Northern Territory, October weather in the city of Darwin is certainly tropical with a daily average high of 91 F.
The cities of Alice Springs and Cairns reach about 86 F. In most other capital cities, the average high can hover around 68 F with Hobart experiencing an average high of approximately 64 F and Sydney averaging 72 F.
Also note that in the desert heart of Australia, daytime temperatures can be very hot and nighttime temperatures can skew exceedingly cold; and in northern Australia, the seasons are more appropriately divided into two seasons: the wet and the dry.
Elsewhere in Australia, with the earth waking up from its winter slumber, blooms dot the fields and gardens with coming of spring.
In Perth, Western Australia, the Kings Park Festival, also popularly known as the Wildflower Festival, usually takes place during the first month of the Australian spring.
Among the New South Wales springtime flower festivals are the Tulip Time Festival in Bowral in the Southern Highlands, Lilac City Festival in Goulburn, Australian Springtime Flora Festival in Kariong near Gosford, Jacaranda Festival in Grafton, and Leura Garden Festival in the Blue Mountains.
In Victoria, the Tesselaar Tulip Festival takes place at a working tulip farm about 25 miles east of Melbourne, while at the Royal Botanic Gardens Cranbourne, the Wildflower Festival is a huge draw for visitors.
Queensland has its Carnival of Flowers in Toowoomba and Tasmania has two tulip festivals, one at Hobart's Royal Tasmanian Botanical Gardens and another at Wynyard northwest of Launceston.
Spring is an ideal time for almost all types of indoor and outdoor activities that are appropriate for the warmer months. You might want to wait until the weather warms up in mid- and late spring before venturing out to the beaches in the southern states. If you are in the North or Western Australia, the hotter temperatures work well for trips to the beach along the Queensland coast and the Great Barrier Reef.
Interestingly, there is not an Australian public holiday celebrated nationally on the same day in the spring season.
Labor Day is in October in the Australian Capital Territory, New South Wales, and South Australia. Meanwhile, other Australian states and the Northern Territory celebrate Labor Day or its equivalent in other seasons.
The Queen's Birthday holiday in honor of Queen Elizabeth II takes place in the spring in Western Australia but in winter in other states and major mainland territories. In actuality, her birthday is April 21.
In northern Tasmania, Recreation Day is a public holiday in November.
