Climate Risk in Geelong, Victoria
Geelong faces increasing risks from climate change, particularly related to flooding, heatwaves, and coastal hazards. The suburb's proximity to the Barwon River and Corio Bay makes it vulnerable to rising sea levels and increased rainfall intensity. Residents should prepare for more frequent extreme weather events and take steps to adapt to a changing climate.

Learn moreAbout Geelong's Climate Risk Profile
Geelong is located on Corio Bay and the Barwon River, making it susceptible to flooding from both riverine and coastal sources. Climate change is expected to increase the frequency and intensity of heavy rainfall events, leading to more frequent and severe flooding. Sea-level rise will also exacerbate coastal flooding, particularly in low-lying areas.
The suburb is also experiencing more frequent and intense heatwaves. Rising temperatures pose a significant risk to vulnerable populations, including the elderly, children, and those with chronic health conditions. The urban heat island effect can further amplify temperatures in built-up areas.
While the risk of bushfire is relatively lower compared to other parts of Victoria, Geelong is not immune. Drier conditions and higher temperatures can increase the risk of bushfires, particularly in areas bordering grasslands and reserves. Residents should be aware of the risks and take steps to prepare their properties.
Coastal erosion is another concern for Geelong, particularly along Corio Bay. Sea-level rise and storm surges can erode coastlines, damaging infrastructure and threatening coastal communities. Protecting and restoring coastal ecosystems can help to mitigate the impacts of coastal erosion.
