About Croydon's Climate Risk Profile

Croydon, located in Melbourne's outer eastern suburbs, is increasingly vulnerable to the impacts of climate change. The primary risks are associated with flooding and heatwaves, with bushfire risk being comparatively lower.

Flooding is a concern due to the suburb's location within the Dandenong Creek catchment. Increased rainfall intensity, driven by climate change, can overwhelm drainage systems and lead to flash flooding. Low-lying areas and properties near waterways are particularly at risk. Residents should be aware of flood warnings and have a plan in place to protect their homes and families.

Heatwaves are becoming more frequent and intense, posing a significant threat to public health. The urban heat island effect exacerbates the problem, trapping heat in built-up areas. Vulnerable populations, such as the elderly, children, and those with chronic health conditions, are most at risk. Staying hydrated, seeking air-conditioned environments, and checking on neighbors are crucial during heatwaves.

While bushfire risk is lower than in some other parts of Victoria, it is still important to be prepared. Grassfires can spread rapidly during dry and windy conditions. Maintaining a fire-safe property, having a bushfire survival plan, and staying informed about fire danger ratings are essential.

Coastal risks are negligible due to Croydon's inland location. However, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could still affect the suburb.
