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 Castle Cove
Flood
Castle Cove has a moderate risk of flooding due to its proximity to waterways and varying elevations. Intense rainfall events can lead to localized flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk in Castle Cove is moderate due to the presence of nearby bushland. While not directly adjacent to large forested areas, ember attack is a potential concern during severe fire weather.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Castle Cove experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. Vulnerable populations may be at risk during extreme heat.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Castle Cove faces a moderate coastal risk due to sea level rise and potential storm surge. While not directly on the open coast, its proximity to Middle Harbour makes it 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 Castle Cove's Climate Risk Profile
Castle Cove, a suburb in Sydney's North Shore, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding due to increased rainfall intensity and proximity to Middle Harbour, rising temperatures leading to more frequent and severe heatwaves, and the potential for coastal inundation from sea level rise and storm surges.
The suburb's location and topography contribute to its flood risk. Intense rainfall events can overwhelm drainage systems, leading to localized flooding. Climate change is expected to exacerbate this risk, with projections indicating more frequent and intense rainfall in the region.
Rising temperatures pose a significant threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions. Heatwaves are expected to become more frequent and severe, increasing the risk of heatstroke and other heat-related illnesses.
Sea level rise poses a long-term threat to properties located near Middle Harbour. While Castle Cove is not directly on the open coast, it is still susceptible to coastal inundation from storm surges and rising sea levels. Planning for future coastal hazards is essential to protect property and infrastructure.
Addressing these climate risks requires a multi-faceted approach, including investments in infrastructure upgrades, community education programs, and adaptation measures at the individual property level. By taking proactive steps, Castle Cove can build resilience and mitigate the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
