Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development
stable

Bushfire

30/100

Eastwood has a low risk of bushfire due to its urban environment and distance from large bushland areas. However, increased temperatures and drier conditions could slightly elevate the risk.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions
increasing

Heat

60/100

Eastwood is expected to experience more frequent and intense heatwaves due to climate change. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

About Eastwood's Climate Risk Profile

Eastwood, a suburb in Sydney's north, is increasingly vulnerable to the impacts of climate change. The primary risks are associated with flooding and heatwaves, which are projected to become more frequent and intense in the coming decades. The suburb's location near waterways makes it susceptible to flooding, especially during periods of heavy rainfall. Climate change is expected to exacerbate this risk by increasing rainfall intensity.

Heatwaves are another significant concern for Eastwood. As temperatures rise, the suburb will experience more days of extreme heat, posing a threat to vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can further amplify the impact of heatwaves.

While bushfire risk is relatively low due to the suburb's urban environment, it is not entirely absent. Increased temperatures and drier conditions could elevate the risk, particularly in areas adjacent to vegetation. Coastal risks are minimal due to Eastwood's distance from the coastline.

To mitigate these risks, Eastwood needs to implement adaptation measures, such as improving drainage infrastructure, increasing vegetation cover, and developing heatwave management plans. These actions will help protect the suburb's residents and infrastructure from the impacts of climate change.
