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 Merrylands
Flood
Merrylands has a moderate risk of flooding due to its proximity to waterways and relatively flat terrain. Several areas are susceptible to flash flooding during heavy rainfall events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The bushfire risk in Merrylands is relatively low due to the urban nature of the suburb. However, some areas near parks and reserves may face a slightly higher risk.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Merrylands experiences a high risk of heatwaves, particularly during the summer months. Urban heat island effect exacerbates the risk.
Key drivers:
- ·Climate change
- ·Urban density
Coastal
Merrylands is located far inland and has a very low risk of coastal hazards.
Key drivers:
- ·Distance from coast

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 Merrylands's Climate Risk Profile
Merrylands, located in Western Sydney, is susceptible to several climate-related risks. The most significant threat is flooding, due to its location near the Parramatta River and other smaller waterways. Heavy rainfall events can lead to flash flooding, impacting homes and businesses. Climate change is expected to increase the intensity and frequency of these rainfall events, exacerbating the flood risk.
The suburb also faces a high risk from heatwaves. The urban environment, with limited green spaces, contributes to the urban heat island effect, making Merrylands particularly vulnerable during periods of extreme heat. This can lead to health issues, especially for vulnerable populations such as the elderly and those with pre-existing conditions.
While the risk of bushfires is relatively low compared to other parts of NSW, it is still a concern, particularly in areas bordering parks and reserves. Dry conditions and strong winds can increase the risk of bushfires spreading into residential areas.
Coastal risks are minimal due to Merrylands' inland location. However, the broader impacts of climate change, such as disruptions to supply chains and economic activity, could still affect the suburb. Addressing these climate risks requires a combination of mitigation and adaptation strategies, including improved drainage infrastructure, increased green spaces, and community awareness programs.
