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 Cudmirrah
Flood
Cudmirrah faces a moderate risk of flooding due to its low-lying coastal location and proximity to Swan Lake. Increased rainfall intensity and rising sea levels are expected to exacerbate flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Cudmirrah has a moderate bushfire risk due to surrounding bushland. Hotter, drier conditions are projected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Cudmirrah is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, especially during summer.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
Cudmirrah is vulnerable to coastal erosion and inundation due to sea level rise. This poses a threat to coastal properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·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 Cudmirrah's Climate Risk Profile
Cudmirrah is a coastal suburb in New South Wales that is increasingly exposed to climate change impacts. The primary risks include flooding from increased rainfall and rising sea levels, bushfires due to hotter and drier conditions, more frequent and intense heatwaves, and coastal erosion threatening properties and infrastructure.
The risk of flooding is exacerbated by the suburb's low-lying topography and proximity to Swan Lake. Climate projections indicate that rainfall intensity will increase, leading to more frequent and severe flood events. Sea level rise will further compound the problem, increasing the risk of coastal inundation.
Bushfire risk is also a concern, as the surrounding bushland provides ample fuel for fires. Hotter and drier conditions are expected to increase the frequency and intensity of bushfires, posing a threat to homes and lives. Residents should be aware of bushfire safety measures and have a plan in place.
Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations, especially the elderly and those with pre-existing health conditions. It is important to stay hydrated, seek shade, and avoid strenuous activity during heatwaves. Coastal erosion is an ongoing issue, with rising sea levels threatening to erode beaches and damage coastal properties.
