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 Longueville
Flood
Longueville is located near the Lane Cove River and Sydney Harbour, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the intensity of rainfall events, potentially worsening flood risks.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
While not immediately adjacent to large bushland areas, Longueville has some bushfire risk due to nearby reserves and potential for ember attack. Drier conditions and higher temperatures could exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Longueville is likely to experience more frequent and intense heatwaves due to climate change. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Key drivers:
- ·Increased temperatures
- ·More frequent heatwaves
Coastal
As a suburb located on the Lane Cove River and close to Sydney Harbour, Longueville is vulnerable to sea level rise and coastal inundation. This could impact waterfront properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·Increased 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 Longueville's Climate Risk Profile
Longueville, a suburb on the Lower North Shore of Sydney, is increasingly vulnerable to the impacts of climate change. Its proximity to the Lane Cove River and Sydney Harbour exposes it to risks from rising sea levels and increased storm surges. The suburb is also likely to experience more frequent and intense heatwaves, posing a threat to public health.
Flooding is a significant concern for Longueville, with potential for both riverine and coastal inundation. Climate change is expected to increase the intensity of rainfall events, leading to more frequent and severe floods. Sea level rise will also exacerbate coastal flooding, particularly during high tides and storm surges.
Heatwaves are another growing threat, with projections indicating a significant increase in the number of hot days per year. This will place strain on infrastructure and emergency services, and pose a risk to vulnerable populations. Residents should take steps to prepare for heatwaves, such as ensuring they have access to air conditioning and staying hydrated.
While bushfire risk is relatively lower compared to other areas, Longueville is still susceptible to ember attack from nearby bushland. Drier conditions and higher temperatures could increase the risk of bushfires in the surrounding region. It is important for residents to maintain their properties and be aware of bushfire safety precautions.
Addressing these climate risks will require a coordinated effort from local government, residents, and businesses. This includes investing in flood mitigation infrastructure, implementing heatwave management plans, and promoting sustainable development practices. By taking proactive steps, Longueville can build resilience to climate change and protect its community.
