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 Randwick
Flood
Randwick faces a moderate risk of flooding, primarily from heavy rainfall events and stormwater runoff. Areas near low-lying coastal regions and waterways are more vulnerable.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Randwick is relatively low due to its urban environment and limited vegetation. However, areas bordering parks and reserves may experience some risk.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Randwick experiences a high risk of heatwaves, particularly during the summer months. Urban areas with limited green space are more susceptible to the urban heat island effect.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Randwick faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. Low-lying coastal areas and beaches are particularly vulnerable.
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 Randwick's Climate Risk Profile
Randwick, located in Sydney's eastern suburbs, is exposed to a range of climate-related risks. Flooding is a significant concern due to increased rainfall intensity and proximity to coastal waterways. The suburb also experiences high heatwave risk, exacerbated by the urban heat island effect. Coastal hazards, including sea level rise and erosion, pose a threat to beachfront properties and infrastructure.
Climate change projections indicate that these risks will intensify in the coming decades. Rising temperatures will lead to more frequent and severe heatwaves, while increased rainfall and sea level rise will exacerbate flooding and coastal erosion. These changes could have significant impacts on property values, infrastructure, and community well-being.
Local authorities are taking steps to address these challenges, including implementing stormwater management strategies, developing heatwave response plans, and investing in coastal protection measures. However, individual residents and businesses also have a role to play in adapting to the changing climate.
This includes measures such as improving home insulation, installing rainwater tanks, and participating in community-based adaptation initiatives. By working together, the community can build resilience and mitigate the impacts of climate change in Randwick.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
