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 Merriangaah
Flood
Flooding may occur due to heavy rainfall and proximity to waterways. Local drainage capacity can be exceeded during intense storms.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development reducing permeable surfaces
Bushfire
The area is susceptible to bushfires due to the presence of nearby bushland. Hot, dry conditions exacerbate the risk.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
The suburb experiences moderately high temperatures during summer, with potential for heatwaves. Vulnerable populations are at risk.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Merriangaah is not exposed to coastal risks.

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 Merriangaah's Climate Risk Profile
Merriangaah, NSW, is exposed to a range of climate-related risks that are projected to intensify in the coming decades. The primary concerns are increased flooding due to more intense rainfall events, heightened bushfire risk from prolonged dry periods and high temperatures, and more frequent and severe heatwaves.
Flooding is a significant concern, as the local drainage infrastructure may struggle to cope with increasingly heavy downpours. Bushfire risk is elevated due to the proximity of bushland, creating a potential for rapid fire spread during hot and windy conditions. Heatwaves pose a threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions.
While coastal risks are minimal, the combined impact of flooding, bushfires, and heatwaves necessitates proactive adaptation measures. These include upgrading drainage infrastructure, implementing bushfire mitigation strategies, and developing heatwave preparedness plans.
Residents should stay informed about weather forecasts and emergency warnings, and take steps to protect their homes and families. Community-level initiatives, such as neighborhood preparedness programs, can also play a crucial role in building resilience to climate change.
