About 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 intensity of rainfall events, leading to more frequent and severe flooding. Sea level rise will also exacerbate coastal flooding and erosion.

Heatwaves are becoming more common and intense in Geelong, posing a significant risk to public health. The urban heat island effect can further amplify temperatures in built-up areas. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk.

While the risk of bushfire is lower compared to other parts of Victoria, it is still a concern, especially in areas bordering grasslands and reserves. Drier conditions and higher temperatures can increase the risk of bushfires.

Coastal erosion is also a concern for Geelong, particularly along Corio Bay. Sea level rise and increased storm surge can lead to further erosion and damage to coastal infrastructure and property.
