Climate Hazard Breakdown for Twenty Forests
Flood
Flooding is a moderate concern in Twenty Forests, with potential for riverine and flash flooding. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Bushfire risk is high in Twenty Forests due to its proximity to bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Heatwaves are a growing concern in Twenty Forests, with potential impacts on vulnerable populations. Climate change is expected to increase the frequency and intensity of heatwaves.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
Coastal risks are low in Twenty Forests due to its inland location. Sea level rise and coastal erosion are not significant threats.
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 Twenty Forests's Climate Risk Profile
Twenty Forests, NSW, is an inland suburb that faces increasing climate-related challenges. The primary risks are associated with flooding and bushfires, both of which are expected to worsen with climate change.
Flooding is a concern due to increased rainfall intensity and potential for flash flooding. Residents should be aware of flood risks and take necessary precautions. Bushfire risk is elevated due to the suburb's proximity to bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires, posing a threat to property and life.
Heatwaves are also a growing concern, particularly for vulnerable populations. Residents should take steps to stay cool during heatwaves and be aware of the signs of heat stress. While coastal risks are low due to the suburb's inland location, the overall climate risk profile suggests the need for proactive adaptation measures.
Addressing these challenges requires a coordinated effort from residents, local government, and emergency services. Implementing adaptation strategies, such as improving drainage infrastructure and managing bushfire fuel loads, can help reduce the impacts of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
