Overall Risk Score

Address-level

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 Crangan Bay

Flood

Crangan Bay faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise

Bushfire

Crangan Bay has a moderate bushfire risk due to surrounding bushland. Hotter, drier conditions are expected to increase the frequency and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Crangan Bay is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

Key drivers:

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

Coastal

Crangan Bay faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. These hazards could impact infrastructure and property values.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

What This Means for Property Owners

Insurance Outlook

Insurance premiums may increase due to climate-related risks.

Price Impact

Properties in high-risk areas may experience a decrease in value.

Buyer Checklist

  • 1.Check flood maps and bushfire prone area designations.
  • 2.Assess the property's vulnerability to heatwaves.
  • 3.Consider the potential impact of sea level rise and coastal erosion.
  • 4.Review insurance options and costs.

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 Crangan Bay's Climate Risk Profile

Crangan Bay, located in the Central Coast region of New South Wales, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to waterways and bushland makes it susceptible to flooding and bushfires, while rising temperatures are expected to increase the frequency and intensity of heatwaves.

Flooding is a significant concern for Crangan Bay, with low-lying areas at particular risk. Climate change is projected to increase rainfall intensity, leading to more frequent and severe floods. This could damage property, disrupt infrastructure, and pose a threat to human safety.

The risk of bushfires is also increasing in Crangan Bay, as hotter, drier conditions create a more favorable environment for fire. Residents should be aware of the risks and take steps to protect their homes and families.

Heatwaves are another growing threat, with the potential to cause heat stress and other health problems, especially among vulnerable populations. It is important to stay cool and hydrated during heatwaves and to check on elderly or sick neighbors.

Coastal erosion and sea level rise also pose a threat to Crangan Bay, although the immediate impact is less severe than flooding, bushfire and heatwave risks. Long-term planning is needed to address these challenges.

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