Climate Hazard Breakdown for Megalong Valley
Flood
Megalong Valley faces a moderate risk of flooding due to its location within a valley and proximity to waterways. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Changes in land use
Bushfire
Megalong Valley has a high bushfire risk due to its location surrounded by dense eucalyptus forests. Dry conditions and strong winds can exacerbate the risk during the bushfire season.
Key drivers:
- ·Drier conditions
- ·Increased fuel load
Heat
Megalong Valley experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and infrastructure.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal

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 Megalong Valley's Climate Risk Profile
Megalong Valley, nestled in the Blue Mountains of New South Wales, is a picturesque area known for its natural beauty. However, the suburb is increasingly vulnerable to the impacts of climate change. Rising temperatures, altered rainfall patterns, and more frequent extreme weather events pose significant challenges to the community and its environment.
Flooding is a concern due to the valley's topography and proximity to waterways. Intense rainfall can lead to flash flooding, impacting homes, infrastructure, and agricultural land. Bushfire risk is also high, with the surrounding eucalyptus forests providing ample fuel during dry periods. The combination of dry conditions, strong winds, and high temperatures creates a dangerous environment for bushfires.
Heatwaves are becoming more frequent and intense, posing health risks to vulnerable populations, such as the elderly and those with chronic illnesses. The increasing heat can also strain infrastructure, such as power grids and transportation systems.
Addressing these climate risks requires a multi-faceted approach, including mitigation efforts to reduce greenhouse gas emissions and adaptation strategies to build resilience. Community awareness, preparedness, and proactive planning are essential to protect Megalong Valley from 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.
