By 2050, Perth will face hotter temperatures, longer heatwaves, more dangerous fire weather, falling winter rain, and a rising sea level.
This will reshape every facet of life across social, economic, and cultural domains in Perth.[1][2][3]
The city's climate trajectory hinges on stronger action.
As of 2025, climate policies lag behind the urgency of scientific warnings, with net-zero ambitions needing tougher, faster implementation to avert the harshest future impacts.[7][8]
The New Heat Era
Perth’s future is set to blaze.
By 2050, the city is projected to endure twice as many days over 35 °C each year, with extreme heat likely to stretch for a whole month or more each summer.[1]
Average temperatures will rise by 1.7–2 °C or more, depending on emissions trajectory, with heatwaves becoming longer, more intense, and deadlier.[2]
Water Scarcity and Drought
Winter and spring rainfall are forecast to drop by up to 29% by mid-century in a high emissions scenario.[2]
The drying trend that’s gripped south-western WA since the 1970s shows no sign of abating.
Heavy rain events may become more intense, but extended droughts will also unravel, reducing inflow into dams, stressing agriculture, and threatening water security.
Rising Seas and Coastal Risk
Sea levels in Perth are locked in to climb 24–30 cm by 2050, even if emissions fall sharply now.[3]
Iconic beaches, river foreshores, and low-lying suburbs such as Elizabeth Quay and sections of East Perth face mounting inundation, a new frontline in the city’s adaptation challenge.
During storms, coastal flooding will intensify, threatening infrastructure and property, with hundreds of homes at future risk.[3]
Hotter, Longer Fire Seasons
Climate change will bring about 40% more days of very high fire danger in Perth by 2050.[6]
Bushfires will start earlier, burn longer, and cover larger areas.
The city will need a dramatic ramp-up of firefighting resources, community preparedness, and hazard reduction strategies to keep pace.
Health and Social Impacts
Heat-related deaths in Perth are projected to rise by more than 60%, with those over 75 most at risk.[4]
Hospital admissions for heat events are set to surge by an estimated 34%, costing the healthcare system over $30 million annually and straining stretched resources.[5]
Vulnerable communities, including the elderly, outdoor workers, and those in poorly insulated housing, face elevated health risks and financial hardship.
Economic Fallout
Perth’s famed outdoor lifestyle and livability will come under threat.
Agricultural supply chains, vital for food and jobs, face disruption from heatwaves and water shortages.
Tourism, recreation, and sectors reliant on green spaces all risk decline, unless urgent measures are undertaken to make the city climate-resilient and inclusive.
Insurance premiums are forecast to rise as extreme weather claims climb, coastal businesses must brace for flooding and erosion.
Political Pace and Public Sentiment
In 2025, government policy targets net zero emissions by 2050—but action is slow and fragmented.[7]
Less than half of Perth’s residents believe current climate strategies will be enough.[8]
Decarbonisation of the grid, expansion of public transport, urban greening, and stricter building codes are essential but lagging.
Political debate is heated, with increasing demand for bolder leadership and faster adaptation plans focusing on community resilience and renewable energy.
Ecological Transformation
As heat intensifies and rainfall drops, urban tree canopy and native biodiversity are under threat.
Coastal erosion will reshape beaches and foreshore habitats, marine environments will warm and acidify, pressuring fisheries and ecosystems.
A new “urban greenbelt” movement is taking shape, with communities pushing to expand tree cover, restore habitat corridors, and bolster local food production.
Cultural Shifts and Community Response
Perth’s culture is already evolving in response to climate anxieties.
Residents increasingly call for adaptation through sustainable design, climate-resilient infrastructure, and more equitable access to green spaces.[8]
There is rising activism among youth, artists, and Indigenous leaders seeking to integrate tradition and technology, demanding a safer, cleaner, and fairer future for all.
The Western Australian Government’s urban greening strategy remains a battleground for public advocacy and policy improvement.
Climate Action: Then and Now
At present, Perth’s climate actions are promising but insufficient.
The State Government commits to net zero by 2050, but renewable adoption rates remain among Australia’s lowest, and political debate clouds bolder interim targets.
Residents and experts agree that only rapid, deep emission cuts, robust climate adaptation, and far-reaching social investment will shield Perth from becoming increasingly “unliveable”.[8]
Perth’s climate is on a knife edge—on action taken between now and 2030 depends whether its future is merely hotter and harder, or the vanguard of global sustainability.
