Learn moreAbout Warrnambool's Climate Risk Profile
Warrnambool, located on the southwest coast of Victoria, is exposed to a range of climate-related risks. The city's proximity to the Merri River and the Southern Ocean makes it particularly vulnerable to flooding and coastal hazards. Climate change is expected to exacerbate these risks, with increased rainfall intensity, sea level rise, and more frequent heatwaves.
Flooding is a significant concern for Warrnambool, with past events causing damage to property and infrastructure. The Merri River can overflow its banks during periods of heavy rainfall, inundating low-lying areas of the city. Sea level rise is also a threat, as it can increase the risk of coastal flooding and erosion.
Heatwaves are becoming more frequent and intense in Warrnambool, posing a risk to public health. The elderly, children, and those with chronic health conditions are particularly vulnerable to heat stress. The urban heat island effect can also exacerbate the impacts of heatwaves in built-up areas.
Coastal erosion is another concern for Warrnambool, with the city's coastline already experiencing significant erosion in some areas. Sea level rise and storm surges are expected to accelerate coastal erosion, threatening infrastructure, property, and natural ecosystems. Addressing these climate risks will require a coordinated effort from government, businesses, and the community.
