Climate Hazard Breakdown for Lacmalac

Flood

Lacmalac faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, potentially worsening flood events.

Key drivers:

  • ·Increased rainfall intensity
  • ·Proximity to waterways

Bushfire

The area around Lacmalac has a high bushfire risk due to the presence of surrounding bushland. Drier conditions and higher temperatures are expected to exacerbate this risk.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Lacmalac experiences moderate heat risk, with increasing average temperatures expected. This could lead to more frequent and intense heatwaves.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

  • 3.Obtain insurance quotes and understand coverage limitations.
  • 4.Consider long-term climate change projections when making investment decisions.

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 Lacmalac's Climate Risk Profile

Lacmalac, NSW, is an area that will likely experience increased climate-related challenges in the coming decades. The primary concerns are related to flooding and bushfire risks, both of which are projected to worsen due to climate change.

Flooding is a significant concern due to the area's proximity to waterways. Increased rainfall intensity, a direct consequence of climate change, will likely lead to more frequent and severe flood events. Residents and property owners should be aware of the potential for property damage and disruption to daily life.

Bushfire risk is also high, with the surrounding bushland creating a substantial threat. Drier conditions and higher temperatures, driven by climate change, will extend the bushfire season and increase the intensity of fires. Preparedness and vigilance are crucial for mitigating this risk.

While heat risk is moderate, rising average temperatures and more frequent heatwaves will impact the community. Vulnerable populations, such as the elderly and those with pre-existing health conditions, will be particularly at risk.

Coastal risks are minimal for Lacmalac, but the broader regional impacts of climate change should still be considered.

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