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 Hillsdale

Flood

Hillsdale faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The area's proximity to Botany Bay increases its vulnerability.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

The bushfire risk in Hillsdale is relatively low due to its urban environment and distance from large bushland areas. However, ember attacks from distant fires remain a potential concern.

Key drivers:

  • ·Dry vegetation
  • ·High winds

Heat

Hillsdale experiences a high risk of heatwaves, particularly during the summer months. Urban heat island effect exacerbates the impact of high temperatures on vulnerable populations.

Key drivers:

  • ·Rising average temperatures
  • ·Urban heat island effect

Coastal

Hillsdale faces a moderate risk from coastal hazards due to its proximity to Botany Bay. Sea level rise and storm surges pose a threat to low-lying areas and infrastructure.

Key drivers:

  • ·Sea level rise
  • ·Increased storm intensity

What This Means for Property Owners

Insurance Outlook

Insurance premiums may increase due to flood and coastal risks.

Price Impact

Properties in low-lying areas may experience price stagnation or decline.

Buyer Checklist

  • 1.Check flood maps and historical flood data
  • 2.Assess property's elevation and drainage
  • 3.Inquire about council's coastal management plans
  • 4.Consider potential impacts of sea level rise
  • 5.Evaluate energy efficiency and cooling options

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 Hillsdale's Climate Risk Profile

Hillsdale, located in the eastern suburbs of Sydney, is increasingly vulnerable to the impacts of climate change. The suburb's proximity to Botany Bay and its low-lying areas make it susceptible to flooding from heavy rainfall and rising sea levels. The urban environment also contributes to the urban heat island effect, exacerbating the impact of heatwaves on residents.

Flooding is a significant concern, with potential for stormwater runoff to overwhelm drainage systems. Climate change projections indicate an increase in rainfall intensity, further increasing the risk of flooding in the area. Coastal hazards, including sea level rise and storm surges, also pose a threat to low-lying areas and infrastructure along the coastline.

Heatwaves are becoming more frequent and intense, posing a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. The urban heat island effect, caused by the concentration of buildings and paved surfaces, further amplifies the impact of high temperatures.

While the risk of bushfires is relatively low due to the suburb's urban environment, ember attacks from distant fires remain a potential concern. Residents should take precautions to protect their homes and be aware of the risk during periods of high fire danger. Adapting to these changing conditions is crucial for ensuring the long-term resilience and sustainability of Hillsdale.
