Climate Hazard Breakdown for Mundijong

Flood

Mundijong faces a moderate risk of flooding, primarily from heavy rainfall events and riverine flooding. The Serpentine River and its tributaries can overflow, impacting low-lying areas.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development increasing runoff

Bushfire

Mundijong has a high bushfire risk due to its proximity to bushland and dry vegetation. Hot, dry summers and strong winds exacerbate the risk.

Key drivers:

  • ·Dry vegetation
  • ·Hotter temperatures

Heat

Mundijong is experiencing more frequent and intense heatwaves. Higher average temperatures pose a risk to vulnerable populations.

Key drivers:

  • ·Global warming
  • ·Urban heat island effect

Coastal

Mundijong is located inland and has a low risk of coastal hazards.

Key drivers:

  • ·Distance from the coast

  • 3.Review insurance options and potential premium increases.
  • 4.Consider long-term climate projections for the area.

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.

About Mundijong's Climate Risk Profile

Mundijong, located in Western Australia, is increasingly vulnerable to the impacts of climate change. The primary risks include bushfires, heatwaves, and flooding. These hazards are projected to intensify in the future, posing challenges to the community and local infrastructure.

Bushfire risk is significant due to the surrounding bushland and dry conditions during the summer months. Heatwaves are becoming more frequent and intense, impacting public health, especially for vulnerable populations. Flooding can occur due to heavy rainfall events and the overflow of the Serpentine River.

Climate projections indicate that these risks will worsen. Higher temperatures, altered rainfall patterns, and more frequent extreme weather events are expected. This necessitates proactive adaptation strategies to mitigate the potential impacts.

Local authorities and residents need to work together to implement measures such as improved bushfire management, heatwave preparedness plans, and flood mitigation infrastructure. Addressing climate change impacts is crucial for ensuring the long-term sustainability and resilience of Mundijong.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
