September and October are a great time to visit Wellington Dam. Spring brings wildflowers into bloom across the jarrah forest, and black cockatoos can be seen moving through the forest.
The forest changes throughout the year, with different plants, wildlife and conditions to see in each season. This guide looks at what to expect throughout the year so you can choose when to visit.
Spring: August to November
Spring is the main wildflower season at Wellington Dam. The first blooms begin to appear from August, with more species coming into flower as the weather warms. By September and October, the jarrah forest understorey is at its most colourful.
Wellington National Park is home to more than 300 flowering plant species, including banksias, grevilleas, triggerplants, sundews and orchids. Spring is also a good time to see the river flowing after winter rain.
What wildflowers to expect
Wildflower timing varies with rainfall and local conditions, so there is no fixed date when everything comes into bloom.
August marks the beginning of the spring display, with early orchids and other flowering plants appearing as conditions warm. Through September and October, more species come into flower across the jarrah forest, with some continuing into November.

Black cockatoos in spring
Spring can also be a good time to look for black cockatoos around Wellington Dam.
Carnaby’s black cockatoos breed inland before moving back towards coastal areas later in the year. Their breeding season generally runs from late July into January. Forest red-tailed black cockatoos also breed from late July to October and feed heavily on native trees such as Marri and Jarrah.
Baudin’s black cockatoo also occurs in the southwest. All three species are threatened, so keep your distance if you see one and avoid approaching birds or using playback.
Practical spring notes
Spring is a popular time to visit Wellington National Park, particularly when wildflowers are in bloom. Weekdays can be a quieter option if you want to spend more time walking or exploring the area.
If you are planning to stay overnight, check current camping availability before travelling, particularly for weekends and school holidays.

Marri flowering and black cockatoos
Marri is an important food source for black cockatoos around southwest WA. The tree generally flowers from December through May, with flowering peaking around February and March.
When Marri is flowering and producing its distinctive honky nuts, it provides food for native birds including black cockatoos. This means summer and early autumn can still be worthwhile for birdwatching, even outside the main spring wildflower season.
For more information about the tree and its role in the local ecosystem, see our guide to Marri trees in Western Australia.
Summer: December to February
Summer at Wellington Dam is hot and dry, so early morning is generally the most comfortable time for walking and birdwatching.
The forest can still be interesting during summer, particularly around flowering native trees. Marri flowers from December through May, with the main flowering period around February and March.
If you are visiting during the warmer months, take plenty of water, wear sun protection and check current park conditions before setting out.
Autumn and winter: March to July
Autumn and winter offer a different experience of Wellington Dam. The weather is cooler, the forest changes with the seasons, and visitor numbers are generally lower than during the warmer months.
Wildflowers are less prominent than in spring, but winter flowering plants can still add colour to the forest. The river and surrounding bushland also change with winter rainfall.
These months can suit visitors who prefer cooler conditions and a quieter walk through the forest.
