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 Sylvania Waters
Flood
Sylvania Waters is highly susceptible to flooding due to its low-lying areas and proximity to waterways. Increased rainfall intensity and sea level rise are expected to exacerbate flood risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
Bushfire risk is moderate due to the presence of surrounding bushland. Hotter, drier conditions are projected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Sylvania Waters is expected to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
As a coastal suburb, Sylvania Waters is vulnerable to sea level rise and coastal erosion. This could lead to inundation of low-lying areas and damage to infrastructure.
Key drivers:
- ·Sea level rise
- ·Storm surge

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 Sylvania Waters's Climate Risk Profile
Sylvania Waters, located in southern Sydney, is particularly vulnerable to the impacts of climate change due to its coastal location and low-lying areas. The primary risks include increased flooding, more frequent and intense heatwaves, and coastal erosion.
Rising sea levels pose a significant threat to properties located near the waterways. Increased rainfall intensity is expected to exacerbate flooding, potentially leading to property damage and disruption to daily life. The urban heat island effect will amplify the impact of heatwaves, particularly for vulnerable residents.
Coastal erosion is another concern, with the potential to damage infrastructure and reduce the amenity of waterfront areas. It is crucial for residents and local authorities to take proactive measures to adapt to these changing conditions.
Addressing these challenges requires a combination of strategies, including improved drainage infrastructure, heat mitigation measures, and coastal protection works. Community awareness and preparedness are also essential to minimize the impacts of extreme weather events.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
