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 Beach
Flood
Avalon Beach faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to stormwater runoff and potential inundation.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Avalon Beach has a high bushfire risk due to its location near significant bushland areas. Dry vegetation and strong winds can exacerbate fire danger during the bushfire season.
Key drivers:
- ·Increased frequency of heatwaves
- ·Drier vegetation
Heat
Avalon Beach experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected in the future.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Avalon Beach faces a moderate coastal risk due to sea level rise and potential erosion. Coastal inundation during storm surges is a concern.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in response to rising climate risks.
Price Impact
Properties in high-risk areas may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Inquire about past flood or bushfire events.
- 4.Consider the cost of insurance and potential for future increases.
- 5.Evaluate the property's energy efficiency and ability to withstand extreme weather events.
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 Beach's Climate Risk Profile
Avalon Beach, located on the Northern Beaches of Sydney, is a coastal suburb known for its beautiful beaches and relaxed lifestyle. However, like many coastal communities, Avalon Beach is increasingly vulnerable to the impacts of climate change.
Flooding is a significant concern, with potential for both riverine and coastal inundation. Intense rainfall events can overwhelm stormwater systems, leading to property damage and disruption. Bushfire risk is also high, particularly during the dry summer months. The suburb's proximity to bushland increases the likelihood of fire impacting homes and infrastructure.
Rising temperatures and more frequent heatwaves pose a threat to public health, especially for vulnerable populations. Coastal erosion and sea level rise are also ongoing challenges, threatening beaches and coastal properties. These risks are projected to worsen in the future, highlighting the need for proactive adaptation measures.
Addressing these challenges requires a coordinated effort from residents, local government, and state agencies. Implementing strategies to reduce greenhouse gas emissions, improve infrastructure resilience, and raise community awareness are crucial for protecting Avalon Beach from the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
