Local Climate Evidence
Flood Evidence
- Nearest Waterway
- Yarra River
- Elevation Range
- 15-70m above sea level
- Flood Zone
- Areas adjacent to Yarra River and Darebin Creek are identified as flood-prone.
While the Yarra River itself poses a risk, smaller creeks and drainage systems can also contribute to localised flooding during heavy rainfall events.

Historical Climate Events
Significant flooding occurred along the Yarra River and its tributaries, impacting low-lying areas of Ivanhoe and surrounding suburbs.
SourceThe Black Saturday bushfires were preceded by an extreme heatwave across Victoria, with temperatures soaring. While Ivanhoe was not directly impacted by fires, the heatwave caused significant health impacts and stress on infrastructure.
SourceHeavy rainfall led to flash flooding in several Melbourne suburbs, including localised flooding in parts of Ivanhoe due to overwhelmed drainage systems.
SourceA prolonged heatwave affected Melbourne, with temperatures exceeding 40°C for several consecutive days, increasing health risks and strain on the power grid.

Projections based on CSIRO and BOM climate modelling. Scenario: RCP 4.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 45 | 5.0(+0.5) | 5.5(+1.0) |
| bushfire | 30 | 3.2(+0.2) | 3.4(+0.4) |
| heat | 65 | 7.5(+1.0) | 8.3(+1.8) |
| coastal | 5 | 0.6(+0.1) | 0.7(+0.2) |
By 2030, Ivanhoe is projected to experience a noticeable increase in overall climate risk, driven primarily by more intense heatwaves and a slight increase in flood potential. Bushfire risk remains relatively stable but requires ongoing monitoring.

Learn moreAbout Ivanhoe's Climate Risk Profile
Ivanhoe, located approximately 10 kilometres northeast of Melbourne's CBD, is a suburb characterised by a mix of residential housing, established parklands, and commercial areas. Its topography varies, with some lower-lying areas closer to the Yarra River and its tributaries, contributing to its flood risk profile. The suburb benefits from good transport links and a range of amenities, making it an attractive place to live.
The primary climate concerns for Ivanhoe revolve around increasing temperatures and the associated risks of heatwaves, as well as potential flooding. The urban heat island effect, exacerbated by development and reduced green cover in certain pockets, contributes to higher temperatures compared to surrounding rural areas. This is projected to worsen with climate change, leading to more frequent and severe heat stress events.
Flood risk in Ivanhoe is primarily linked to the Yarra River and its smaller tributaries that traverse or border the area. While major flood events are infrequent, localised flash flooding can occur during intense rainfall, particularly in areas with higher impervious surfaces and lower elevations. Understanding the specific flood mapping for Ivanhoe is crucial for residents in these zones.
Bushfire risk, while not as prominent as in outer-suburban or regional areas, is still a consideration. Ivanhoe is adjacent to several significant green spaces and parklands, including parts of the Yarra Valley. These areas, while providing valuable amenity, can act as fuel sources during dry periods, posing a risk to nearby properties, especially during extreme weather conditions.
Coastal impacts are not a direct concern for Ivanhoe due to its inland location. However, broader climate change effects such as changes in rainfall patterns and extreme weather events can indirectly influence the suburb through impacts on infrastructure and regional ecosystems. Adaptation strategies should focus on building resilience to heat and managing water effectively.
Overall, Ivanhoe presents a moderate climate risk profile. Residents and local authorities are encouraged to focus on heat adaptation measures, understanding local flood risks, and maintaining preparedness for extreme weather events. Proactive planning and community engagement are key to mitigating these challenges.

Frequently Asked Questions
What is the main flood risk for Ivanhoe residents?
The main flood risk for Ivanhoe is associated with the Yarra River and its tributaries, as well as localised flash flooding during intense rainfall events, particularly in lower-lying areas.
How will climate change affect heatwaves in Ivanhoe?
Climate change is projected to increase the frequency, intensity, and duration of heatwaves in Ivanhoe, exacerbating the urban heat island effect and posing greater health risks.
Is Ivanhoe considered a high-risk bushfire area?
Ivanhoe is generally considered to have a low to moderate bushfire risk, primarily concentrated in areas where residential properties interface with significant parklands and bushland reserves.
What can I do to prepare my home for heatwaves in Ivanhoe?
To prepare for heatwaves, consider improving home insulation, installing efficient cooling systems, using block-out curtains, and ensuring adequate ventilation. Planting deciduous trees can also provide valuable shade.
Does Ivanhoe experience coastal flooding or sea-level rise impacts?
No, Ivanhoe is located too far inland to be directly affected by coastal flooding or sea-level rise. Its climate risks are primarily related to heat, flooding from rivers/creeks, and bushfire at the urban interface.
Where can I find the official flood map for my property in Ivanhoe?
You can find the official flood maps for Ivanhoe on the City of Banyule's website under their Planning and Building services section, or by contacting the council directly.
