Learn moreAbout Cheltenham's Climate Risk Profile
Cheltenham, located in Victoria, is increasingly vulnerable to the impacts of climate change. The suburb faces a combination of risks, including flooding from heavy rainfall and nearby waterways, heatwaves with rising average temperatures, and coastal hazards due to its proximity to Port Phillip Bay.
Flooding is a significant concern, with potential for property damage and disruption to daily life. The increasing intensity of rainfall events, coupled with urban development that reduces natural drainage, exacerbates this risk. Coastal inundation due to sea level rise and storm surges also poses a threat, particularly to low-lying areas.
Heatwaves are becoming more frequent and intense, posing a health risk to vulnerable populations, such as the elderly and those with pre-existing medical conditions. The urban heat island effect further amplifies the impact of heatwaves in densely built-up areas.
While the bushfire risk is relatively lower compared to some other areas in Victoria, it is still present due to nearby reserves and parks. Drier conditions and higher temperatures can increase the risk of bushfires spreading into the suburb.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Mitigation efforts focus on reducing greenhouse gas emissions to slow down the pace of climate change, while adaptation measures aim to build resilience and minimize the impacts of unavoidable changes.
