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 Merredin
Flood
Merredin faces a moderate risk of flooding, primarily from heavy rainfall events causing flash flooding and riverine flooding along the Merredin River. Local infrastructure may be vulnerable.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Merredin is located in a region with a high bushfire risk due to dry vegetation and hot, dry summers. Grassfires are a significant concern.
Key drivers:
- ·Dry vegetation
- ·Hot summers
Heat
Merredin experiences high temperatures during summer, leading to heatwave conditions. Vulnerable populations are at risk.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Merredin is located inland and does not face any direct 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 Merredin's Climate Risk Profile
Merredin, located in the Wheatbelt region of Western Australia, is susceptible to a range of climate-related risks. The primary concerns are flooding from intense rainfall events, bushfires during the hot, dry summers, and heatwaves that can impact vulnerable populations.
Flooding in Merredin is typically caused by heavy rainfall events that can overwhelm local drainage systems and cause flash flooding. The Merredin River can also contribute to riverine flooding during periods of sustained rainfall. Climate change is projected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.
Bushfires are a significant threat to Merredin due to the surrounding dry vegetation and hot, windy conditions during summer. Grassfires can spread rapidly and pose a risk to properties and infrastructure. Maintaining firebreaks and implementing bushfire preparedness measures are crucial for mitigating this risk.
Heatwaves are becoming more frequent and intense in Merredin, posing a health risk to vulnerable populations, such as the elderly and those with chronic health conditions. Implementing heat action plans and providing access to cooling centers can help reduce the impact of heatwaves.
While Merredin is located inland and does not face direct coastal risks, the broader impacts of climate change, such as disruptions to agriculture and water resources, can still affect the community.
