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 Cumberland Reach

Flood

Cumberland Reach is at a high risk of flooding due to its proximity to the Hawkesbury River and low-lying areas. Riverine flooding is the primary concern.

Key drivers:

  • ·Increased rainfall intensity
  • ·Rising river levels

Bushfire

Bushfire risk is moderate due to surrounding vegetation. Grassfires are also a potential hazard.

Key drivers:

  • ·Dry vegetation
  • ·Hot and windy conditions

Heat

Heatwave risk is increasing, with more frequent and intense heat events projected. Vulnerable populations are at higher risk.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

Coastal risk is low as the suburb is not directly on the coast, but sea level rise could affect the Hawkesbury River.

Key drivers:

  • ·Sea level rise
  • ·Increased storm surge

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 Cumberland Reach's Climate Risk Profile

Cumberland Reach, located in New South Wales, is susceptible to several climate-related risks. The most significant threat is flooding due to its location near the Hawkesbury River. Climate change is expected to increase rainfall intensity, leading to more frequent and severe flooding events.

Bushfire risk is moderate, with surrounding bushland posing a threat during dry and windy conditions. While not as immediate as flooding, residents should remain vigilant and prepared for potential bushfire events.

Heatwaves are becoming more frequent and intense, posing a significant risk to vulnerable populations. Rising average temperatures and the urban heat island effect exacerbate this risk. It is crucial to implement measures to mitigate heat exposure and ensure access to cooling during heatwaves.

While coastal risks are relatively low, sea level rise could indirectly affect the suburb through the Hawkesbury River. Changes in river levels and increased storm surge could exacerbate flooding events. Monitoring and adaptation strategies are necessary to address these potential impacts.

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