Climate Hazard Breakdown for Markwell
Flood
Markwell faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise

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 Markwell's Climate Risk Profile
Markwell, NSW, is situated in a region that is increasingly vulnerable to the impacts of climate change. The primary concerns for this suburb are flooding, bushfires, and heatwaves. Changes in rainfall patterns and rising temperatures are expected to intensify these hazards, posing challenges to the local community and infrastructure.
Flooding is a significant concern due to the proximity of waterways and low-lying areas. Increased rainfall intensity can lead to more frequent and severe flood events, potentially disrupting transportation, damaging property, and posing risks to human safety. The local council and emergency services are working to improve flood management strategies, but further investment in infrastructure and community preparedness is needed.
Bushfire risk is also a factor, with surrounding bushland creating a potential source of ignition. Hotter, drier conditions increase the likelihood of bushfires, which can threaten homes and livelihoods. Residents are encouraged to maintain their properties, clear vegetation, and have a bushfire survival plan in place.
Heatwaves are becoming more frequent and intense, posing a particular risk to vulnerable populations. The elderly, young children, and those with chronic health conditions are especially susceptible to heat stress. Access to cooling centers and public awareness campaigns are important strategies for mitigating the health impacts of heatwaves.
While Markwell is not directly on the coast, indirect impacts from coastal changes are possible. It is important for the community to stay informed about climate change projections and adaptation measures to ensure long-term resilience.
