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 Swansea
Flood
Swansea is located near Lake Macquarie and the ocean, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Swansea has some areas of bushland interface, increasing the risk of bushfires. Hotter and drier conditions due to climate change are expected to lengthen the bushfire season and increase the intensity of fires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Swansea is projected to experience more frequent and intense heatwaves due to climate change. This can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
Swansea's coastal location makes it vulnerable to sea level rise and coastal erosion. Climate change is expected to exacerbate these risks, potentially impacting infrastructure and coastal ecosystems.
Key drivers:
- ·Thermal expansion of seawater
- ·Melting glaciers and ice sheets

Primary Drivers
- ·Thermal expansion of seawater
- ·Melting glaciers and ice sheets
bushfire Risk
Swansea has some areas of bushland interface, increasing the risk of bushfires. Hotter and drier conditions due to climate change are expected to lengthen the bushfire season and increase the intensity of fires.
Primary Drivers
- ·Increased temperatures
- ·Drier conditions
- ·Increased fuel load
What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase in areas at high risk of flooding and coastal erosion.
Price Impact
Properties in vulnerable locations may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and coastal erosion risk assessments.
- 2.Assess the property's vulnerability to bushfires.
- 3.Consider the potential impact of climate change on insurance premiums.
- 4.Inquire about council plans for climate change adaptation.
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 Swansea's Climate Risk Profile
Swansea, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to Lake Macquarie and the coast exposes it to a range of hazards, including flooding, coastal erosion, and rising sea levels.
Climate change is expected to exacerbate these existing risks. Increased rainfall intensity will likely lead to more frequent and severe flooding events. Rising temperatures will result in more heatwaves, posing a threat to public health. Sea level rise will further increase the risk of coastal erosion and inundation.
The community needs to take proactive steps to adapt to these changing conditions. This includes investing in flood mitigation infrastructure, implementing heatwave management plans, and protecting coastal ecosystems. Individual households can also take steps to reduce their vulnerability, such as raising homes above flood levels and installing energy-efficient cooling systems.
Addressing climate change requires a collaborative effort from all levels of government, the private sector, and the community. By working together, Swansea can build a more resilient and sustainable future.
