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 Marrickville
Flood
Marrickville faces a moderate risk of flooding due to its proximity to the Cooks River and other waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Marrickville has a relatively low bushfire risk due to its urban environment and distance from large bushland areas. However, increased temperatures and drier conditions could slightly elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Marrickville is susceptible to heatwaves, particularly during summer. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
Marrickville is located inland and has a very low risk of coastal inundation or erosion. Sea level rise is not expected to directly impact the suburb.
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 Marrickville's Climate Risk Profile
Marrickville, located in the inner west of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to the Cooks River makes it susceptible to flooding, which is expected to worsen with increased rainfall intensity.
Heatwaves are another significant concern for Marrickville residents. The urban environment contributes to the urban heat island effect, exacerbating the impact of rising temperatures. Vulnerable populations, such as the elderly and those with chronic health conditions, are particularly at risk.
While Marrickville is not directly exposed to coastal hazards, the broader Sydney region will experience sea level rise and increased storm surges, which could indirectly affect the suburb through economic and social disruptions.
Addressing these climate risks requires a multi-faceted approach, including improved stormwater management, increased green spaces to mitigate the urban heat island effect, and community awareness programs to prepare residents for extreme weather events. Individual actions, such as reducing energy consumption and water usage, can also contribute to a more sustainable future for Marrickville.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
