Climate Hazard Breakdown for Duffys Forest

Flood

Duffys Forest faces a moderate risk of flooding, primarily from heavy rainfall events and localised overland flow. Properties in low-lying areas are more vulnerable.

Key drivers:

  • ·Increased rainfall intensity
  • ·Urban development

Bushfire

Duffys Forest has a high bushfire risk due to its proximity to dense bushland. Hot, dry conditions and strong winds can exacerbate the risk during bushfire season.

Key drivers:

  • ·Dry vegetation
  • ·High temperatures

Heat

Duffys Forest experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events expected in the future.

Key drivers:

  • ·Climate change
  • ·Urban heat island effect

Coastal

Duffys Forest has a low coastal risk due to its inland location. Sea level rise and coastal erosion are not significant threats.

Key drivers:

  • ·Distance from coast

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 Duffys Forest's Climate Risk Profile

Duffys Forest, located in the Northern Beaches region of New South Wales, is characterized by its lush bushland and semi-rural setting. This environment contributes to a heightened risk of bushfires, particularly during the dry summer months. Climate change is projected to increase the frequency and intensity of bushfire events, posing a significant threat to properties and residents.

Flooding is another concern for Duffys Forest, especially in low-lying areas. Heavy rainfall can lead to localized flooding and disruptions to infrastructure. Climate change is expected to increase rainfall intensity, further elevating the risk of flooding.

Rising temperatures and more frequent heatwaves are also anticipated to impact Duffys Forest. These changes can lead to increased heat stress, particularly for vulnerable populations. Residents should take precautions to stay cool and hydrated during hot weather.

While coastal risks are relatively low due to the suburb's inland location, the broader Northern Beaches region is susceptible to sea level rise and coastal erosion. These factors could indirectly affect Duffys Forest through impacts on regional infrastructure and services. It is important for residents to stay informed about climate change projections and take steps to adapt to the changing environment.

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