Climate Hazard Breakdown for Farnham

Flood

Farnham faces a moderate risk of flooding due to its proximity to the Hawkesbury River and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

Key drivers:

  • ·Increased rainfall intensity
  • ·Rising river levels

Bushfire

Bushfire risk in Farnham is moderate, with surrounding bushland posing a threat during dry periods. Climate change is projected to increase the frequency and intensity of bushfires.

Key drivers:

  • ·Increased temperatures
  • ·Drier conditions

Heat

Farnham experiences high temperatures during summer, with heatwaves becoming more frequent and intense due to climate change. This poses a risk to vulnerable populations.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

Farnham is not directly exposed to coastal risks, as it is located inland. Sea level rise and coastal erosion are not significant concerns for this suburb.

Key drivers:

  • ·Distance from the 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 Farnham's Climate Risk Profile

Farnham, located in the Hawkesbury region of New South Wales, is susceptible to several climate-related hazards. The suburb's proximity to the Hawkesbury River makes it vulnerable to flooding, particularly during periods of heavy rainfall. Climate change projections indicate an increase in rainfall intensity, which could lead to more frequent and severe flood events.

Bushfire risk is another concern for Farnham, with surrounding bushland posing a threat during dry periods. Rising temperatures and drier conditions, driven by climate change, are expected to increase the frequency and intensity of bushfires in the region. Residents should be prepared for potential bushfire threats and take necessary precautions.

Heatwaves are also a significant concern for Farnham, with high temperatures during summer posing a risk to vulnerable populations. Climate change is projected to increase the frequency and intensity of heatwaves, exacerbating the health impacts on residents. It is important to stay hydrated and seek shelter during periods of extreme heat.

While Farnham is not directly exposed to coastal risks, the broader Hawkesbury region may experience indirect impacts from sea level rise and coastal erosion. It is essential to consider these broader regional impacts when planning for climate change adaptation.
