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 | 4.2 | 4.5(+0.3) | 4.9(+0.7) |
| heat | 7.1 | 7.9(+0.8) | 8.6(+1.5) |
| coastal | 1.5 | 1.5 | 1.5 |
By 2030, Midland is projected to experience a notable increase in heatwave frequency and intensity, along with a moderate increase in flood risk due to more intense rainfall events. Bushfire risk is also expected to rise slightly.

Learn moreAbout Midland's Climate Risk Profile
Midland, located in Western Australia, is projected to experience increasing climate-related challenges in the coming decades. The primary risks stem from increased flooding due to more intense rainfall events and rising temperatures leading to more frequent and severe heatwaves. The suburb's proximity to the Swan River makes it vulnerable to flooding, and this vulnerability is expected to increase with climate change.
Heatwaves pose a significant threat to the health and well-being of Midland residents, particularly vulnerable populations such as the elderly and those with chronic health conditions. The urban heat island effect can further amplify these risks, making adaptation measures crucial.
While Midland is not directly exposed to coastal risks, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could indirectly affect the suburb. Therefore, a comprehensive approach to climate adaptation is essential.
Addressing these challenges requires a combination of mitigation and adaptation strategies. Mitigation efforts should focus on reducing greenhouse gas emissions, while adaptation measures should aim to build resilience to the impacts of climate change. This includes investing in flood defenses, improving urban planning to reduce the urban heat island effect, and implementing public health programs to protect vulnerable populations during heatwaves.
