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 Port Arthur

Flood

Port Arthur faces a moderate risk of flooding, primarily from heavy rainfall events and potential coastal inundation. The low-lying areas near the coast and the historic site are particularly vulnerable.

Key drivers:

  • ·Increased rainfall intensity
  • ·Sea level rise

Bushfire

Port Arthur has a notable bushfire risk due to its proximity to extensive bushland. Hot, dry summers and strong winds can exacerbate the risk of bushfires impacting the town.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Port Arthur experiences a relatively low risk from heatwaves compared to other parts of Australia. However, increasing average temperatures may lead to more frequent and intense heat events in the future.

Key drivers:

  • ·Rising average temperatures
  • ·Climate change

Coastal

Port Arthur is highly vulnerable to coastal hazards due to its location on the coast. Sea level rise, coastal erosion, and storm surges pose significant threats to infrastructure and the historic site.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

What This Means for Property Owners

Insurance Outlook

Premiums are likely to increase due to climate risks.

Price Impact

Properties closer to the coast may experience price reductions.

Buyer Checklist

  • 1.Check flood maps and bushfire prone area designations.
  • 2.Assess the property's vulnerability to coastal hazards.
  • 3.Inquire about insurance costs and coverage.
  • 4.Consider long-term climate risks when making a purchase decision.

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 Port Arthur's Climate Risk Profile

Port Arthur, a historic town on the Tasman Peninsula, is increasingly exposed to climate change impacts. The most pressing threat is coastal inundation due to sea level rise and storm surges. The town's low-lying coastal location makes it highly vulnerable, potentially damaging the historic site and other infrastructure.

Bushfire risk is another significant concern. The surrounding bushland creates a high fuel load, and hot, dry summers increase the likelihood of bushfires. Changes in rainfall patterns and increased temperatures could further exacerbate this risk.

While heatwave risk is relatively lower compared to other regions, increasing average temperatures may lead to more frequent and intense heat events in the future. This could impact the health of residents and visitors, particularly during peak tourist season.

Flooding from heavy rainfall events also poses a risk, especially in low-lying areas. Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.

Addressing these climate risks requires a comprehensive adaptation strategy that includes coastal protection measures, bushfire management, and heatwave preparedness. Protecting the historic site and ensuring the safety of residents and visitors are paramount.

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