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 Merriwagga
Flood
Merriwagga faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. The flat terrain contributes to slower drainage, increasing flood duration.
Key drivers:
- ·Heavy rainfall
- ·Flat topography
Bushfire
The area around Merriwagga is prone to bushfires, particularly during hot and dry summer months. Grasslands and sparse vegetation surrounding the town increase the risk of fire spread.
Key drivers:
- ·Dry climate
- ·Grassland vegetation
Heat
Merriwagga experiences high temperatures during summer, leading to heatwave conditions. Climate change is expected to exacerbate these conditions, increasing the frequency and intensity of heatwaves.
Key drivers:
- ·Climate change
- ·High average temperatures
Coastal
Merriwagga is located far inland and does not face any direct coastal risks such as sea level rise or coastal erosion.
Key drivers:
- ·Inland location

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to bushfire and flood risk.
Price Impact
Properties in high-risk areas may experience price stagnation or decline.
Buyer Checklist
- 1.Check flood maps and bushfire prone area designations.
- 2.Assess property's vulnerability to heatwaves.
- 3.Inquire about insurance costs and coverage.
- 4.Consider potential impacts of climate change on property value.
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 Merriwagga's Climate Risk Profile
Merriwagga, located in the Riverina region of New South Wales, is susceptible to several climate-related hazards. The town's inland location means it is shielded from coastal risks, but it is increasingly vulnerable to heatwaves and bushfires. Changes in rainfall patterns may also increase flood risk.
The region experiences hot, dry summers, which contribute to a high bushfire risk. The surrounding grasslands and sparse vegetation provide fuel for fires, and strong winds can quickly spread flames. Climate change is projected to increase the frequency and intensity of heatwaves, further exacerbating the fire risk.
Flooding is another concern for Merriwagga, particularly during periods of heavy rainfall. The flat terrain around the town can lead to slower drainage, increasing the duration of floods. While major river systems are not a direct threat, local waterways and overland flow can cause significant damage.
Adapting to these climate challenges will require a combination of strategies, including improved building standards, enhanced emergency preparedness, and community awareness programs. Reducing greenhouse gas emissions is also crucial to mitigating the long-term impacts of climate change.
