Climate Outlook to 2050
Projections based on CSIRO and BOM climate modelling. Scenario: RCP4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 6.0 | 6.2(+0.2) | 6.5(+0.5) |
| bushfire | 4.0 | 4.1(+0.1) | 4.3(+0.3) |
| heat | 7.0 | 7.5(+0.5) | 8.8(+1.8) |
| coastal | 1.0 | 1.0 | 1.0 |
Under a moderate emissions scenario, Ballarat is projected to experience a slight increase in overall climate risk, primarily driven by increased heatwave frequency and intensity. Flood risk is also expected to increase due to changes in rainfall patterns.

Learn moreAbout Ballarat's Climate Risk Profile
Ballarat, located in Victoria, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding, heatwaves, and bushfires. Changes in rainfall patterns and rising temperatures are expected to exacerbate these hazards.
Flooding is a significant concern due to the city's location in a valley and its proximity to waterways. Increased rainfall intensity can overwhelm drainage systems and cause property damage. The local council is working to improve flood management infrastructure, but further action is needed.
Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations, particularly the elderly and those with pre-existing conditions. Urban areas within Ballarat experience the urban heat island effect, further amplifying temperatures.
Bushfire risk is moderate, with some areas bordering bushland. Drier conditions and higher temperatures increase the likelihood of bushfires. Residents need to be prepared and aware of fire safety measures.
While Ballarat is not directly exposed to coastal risks, the broader impacts of climate change, such as economic disruption and population displacement, could indirectly affect the city. Addressing climate change requires a coordinated effort from individuals, businesses, and government.
