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 Chain Valley Bay
Flood
Chain Valley Bay is susceptible to flooding from heavy rainfall and nearby waterways. Climate change is expected to increase the intensity of rainfall events, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The area surrounding Chain Valley Bay has some bushfire risk due to nearby bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Chain Valley Bay is projected 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 greenhouse gas emissions
- ·Urban heat island effect
Coastal
Chain Valley Bay faces some coastal risks due to its proximity to the coast. Sea level rise and storm surges could lead to erosion and inundation of low-lying areas.
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 Chain Valley Bay's Climate Risk Profile
Chain Valley Bay is located on the Central Coast of New South Wales and is exposed to a range of climate-related hazards. The suburb is particularly vulnerable to flooding due to its low-lying topography and proximity to waterways. Climate change is expected to increase the intensity of rainfall events, leading to more frequent and severe flooding.
Bushfire risk is also a concern, as the area is surrounded by bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires, posing a threat to homes and infrastructure.
Heatwaves are another significant risk, especially for vulnerable populations. Climate change is projected to increase the frequency and intensity of heatwaves, leading to heat stress and other health problems.
Finally, Chain Valley Bay faces coastal risks due to sea level rise and storm surges. These hazards could lead to erosion and inundation of low-lying areas, damaging property and infrastructure.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
