Climate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 6.5 | 7.0(+0.5) | 7.5(+1.0) |
| bushfire | 3.0 | 3.3(+0.3) | 3.5(+0.5) |
| heat | 7.0 | 7.7(+0.7) | 8.2(+1.2) |
| coastal | 4.0 | 4.2(+0.2) | 4.5(+0.5) |
By 2030, Maribyrnong is projected to experience more frequent and intense heatwaves, increased rainfall leading to higher flood risk, and a slight increase in bushfire risk. Coastal impacts remain relatively low but are still a concern.

Learn moreAbout Maribyrnong's Climate Risk Profile
Maribyrnong, located in metropolitan Melbourne, is particularly vulnerable to the impacts of climate change due to its proximity to the Maribyrnong River and its urban environment. The primary concerns are increased flooding and more intense heatwaves.
The risk of flooding is expected to rise with more intense rainfall events. The Maribyrnong River poses a significant threat, and low-lying areas are particularly susceptible. Climate change projections indicate that these events will become more frequent and severe.
Heatwaves are also a major concern for Maribyrnong. The urban heat island effect exacerbates the impact of rising temperatures, making densely populated areas particularly vulnerable. Reduced green space further contributes to this issue.
While bushfire risk is relatively low compared to other regions in Victoria, it is still expected to increase slightly due to hotter and drier conditions. Coastal risks are indirect but could affect the broader Melbourne area through sea level rise and storm surges.
Addressing these challenges requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing down climate change, while local adaptation measures can help protect residents and infrastructure from the impacts that are already locked in.
