About Sandringham's Climate Risk Profile

Sandringham, located on the coast of Port Phillip Bay, faces a number of climate-related challenges. The most significant risk is coastal inundation due to sea level rise and storm surges. This could lead to property damage, infrastructure disruption, and displacement of residents.

Flooding from heavy rainfall and stormwater runoff is also a concern, particularly in low-lying areas. Increased rainfall intensity, driven by climate change, is expected to exacerbate this risk. The urban environment can further contribute to flooding due to increased impervious surfaces.

Rising temperatures and more frequent heatwaves pose a growing threat to the health and well-being of Sandringham residents. The urban heat island effect can amplify these impacts, particularly for vulnerable populations such as the elderly and those with chronic health conditions.

While the risk of bushfire is relatively low, it is not negligible, especially during dry and windy conditions. Residents should be aware of the potential for bushfires and take appropriate precautions. The changing climate may also bring new and unexpected challenges, requiring ongoing monitoring and adaptation.
