Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Avalon
Flood
Avalon faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Avalon has a high bushfire risk due to its location surrounded by bushland. Hot, dry conditions and strong winds can exacerbate the risk.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Avalon experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Avalon faces a moderate coastal risk due to sea level rise and potential erosion. Coastal inundation during storms is a concern.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Avalon's Climate Risk Profile
Avalon, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to bushland elevates the risk of bushfires, while its coastal location makes it susceptible to sea level rise and coastal erosion.
Flooding is another significant concern for Avalon, with intense rainfall events capable of causing flash flooding in low-lying areas. Climate change is expected to exacerbate these risks, leading to more frequent and severe weather events.
Rising temperatures and heatwaves will also pose challenges for residents, particularly the elderly and vulnerable. The urban heat island effect may further amplify these impacts.
Addressing these climate risks requires proactive adaptation measures, including improved building standards, enhanced emergency preparedness, and sustainable land management practices. Community engagement and awareness are also crucial for building resilience.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
