About Dandenong's Climate Risk Profile

Dandenong, located in metropolitan Melbourne, is projected to experience significant climate changes in the coming decades. The primary risks are associated with increased flooding due to more intense rainfall events and rising temperatures leading to more frequent and severe heatwaves.

The suburb's location within the Dandenong Creek catchment makes it vulnerable to flooding, particularly as rainfall patterns intensify. Aging drainage infrastructure and increased urban development further exacerbate this risk. Residents and businesses should prepare for potential disruptions and property damage.

Heatwaves are also a growing concern, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. The urban heat island effect can amplify temperatures, making Dandenong hotter than surrounding areas. Increased green spaces and improved building design can help mitigate this effect.

While the risk of bushfire is relatively low, it is not negligible, especially in areas bordering bushland. Residents should be aware of fire safety measures and maintain their properties to reduce fire hazards.

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