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 Bronte
Flood
Bronte faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The proximity to Bronte Beach and the natural drainage patterns contribute to this risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Bronte is relatively low due to its urban environment and limited vegetation. However, nearby parks and reserves could pose a threat during extreme conditions.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Bronte experiences a high heat risk, particularly during summer months. Increased frequency and intensity of heatwaves can impact vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Coastal erosion and sea level rise pose a moderate threat to Bronte's coastal areas. Infrastructure and properties near the beach are vulnerable to these impacts.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Bronte's Climate Risk Profile
Bronte, a coastal suburb in Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include heatwaves, flooding, coastal erosion, and bushfire, although the latter is less pronounced than the others. Rising global temperatures are contributing to more frequent and intense heatwaves, posing a significant threat to public health, especially among vulnerable populations.
Flooding is another concern, with heavy rainfall events and stormwater runoff causing potential damage to properties and infrastructure. The suburb's proximity to Bronte Beach and natural drainage patterns exacerbate this risk. Sea level rise and coastal erosion threaten the coastline, potentially impacting beachfront properties and recreational areas.
While bushfire risk is relatively lower compared to other parts of NSW, nearby parks and reserves could still pose a threat during extreme conditions. It is crucial for residents to stay informed and take necessary precautions to mitigate these risks.
Adapting to these changes requires a multi-faceted approach, including infrastructure improvements, community awareness programs, and individual preparedness measures. By understanding the specific risks and taking proactive steps, Bronte can enhance its resilience to the impacts of climate change and ensure a sustainable future for its residents.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
