Hazard Breakdown

Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.

Climate Hazard Breakdown for Wallis Lake

Flood

Wallis Lake is susceptible to flooding due to its low-lying areas and proximity to Wallis Lake. Increased rainfall intensity could exacerbate flood risks.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise

Bushfire

Bushfire risk is present due to surrounding vegetation. Drier conditions and higher temperatures could increase the likelihood and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Wallis Lake is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations and infrastructure.

Key drivers:

  • ·Increased greenhouse gas emissions
  • ·Urban heat island effect

Coastal

Coastal erosion and inundation are potential threats due to sea level rise. Infrastructure and properties near the coastline are particularly vulnerable.

Key drivers:

  • ·Sea level rise
  • ·Storm surges

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 Wallis Lake's Climate Risk Profile

Wallis Lake, located in New South Wales, is increasingly vulnerable to the impacts of climate change. The region is expected to experience more frequent and intense heatwaves, leading to potential health risks for vulnerable populations. Changes in rainfall patterns may also increase the risk of both flooding and drought.

Sea level rise poses a significant threat to coastal areas within Wallis Lake, potentially leading to erosion and inundation of low-lying properties. Bushfire risk is also a concern, with drier conditions and higher temperatures increasing the likelihood of fires in surrounding areas.

The local community needs to take proactive steps to adapt to these changing conditions. This includes investing in infrastructure improvements to mitigate flood risks, implementing strategies to reduce the urban heat island effect, and developing emergency response plans for extreme weather events.

Individual property owners can also take steps to protect their homes and families. This includes improving home insulation, installing rainwater tanks, and creating defensible spaces around properties to reduce bushfire risk. Staying informed about weather forecasts and emergency warnings is also crucial.

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