Hazard Breakdown
Climate Hazard Breakdown for Croydon
Flood
Croydon faces a moderate risk of flooding due to its location within the Dandenong Creek catchment. Intense rainfall events can lead to flash flooding, particularly in low-lying areas and near waterways.
Key drivers:
- ·Increased rainfall intensity
- ·Urbanisation
Bushfire
Croydon has a relatively low bushfire risk compared to other areas in Victoria, but is still susceptible due to proximity to bushland areas. Grassfires can also pose a threat during dry periods.
Key drivers:
- ·Dry vegetation
- ·Wind
Heat
Croydon is experiencing an increase in the frequency and intensity of heatwaves. This poses a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Croydon is located far inland and has negligible risk from coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Distance from coast
Wind
Moderate wind risk — cold fronts and gusty winds
Storm
Moderate storm risk — severe thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — heating and cooling needs

Learn moreAbout 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.
