Climate Hazard Breakdown for Hawkesbury
Flood
Hawkesbury is highly susceptible to flooding due to its location on the Hawkesbury River floodplain. The risk is projected to increase with more intense rainfall events.
Key drivers:
- ·Increased rainfall intensity
- ·Riverine flooding
Bushfire
The area surrounding Hawkesbury has a significant bushfire risk due to the presence of extensive bushland. Hot, dry conditions exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Hawkesbury experiences high temperatures during summer, and the number of extreme heat days is projected to increase, posing a risk to vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
Hawkesbury is not directly exposed to coastal risks, but sea level rise and storm surges could indirectly affect the region through economic and social disruptions.

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.

Learn moreAbout Hawkesbury's Climate Risk Profile
Hawkesbury, located in New South Wales, is a region characterized by its rich history and diverse landscapes. However, it is increasingly facing challenges posed by climate change.
The most significant risk to Hawkesbury is flooding. The Hawkesbury River, which runs through the region, is prone to flooding during periods of heavy rainfall. Climate change is expected to increase the intensity and frequency of these rainfall events, leading to more severe and frequent flooding.
Bushfires are another major concern for Hawkesbury. The region is surrounded by extensive bushland, which provides ample fuel for fires. Hot, dry conditions, exacerbated by climate change, increase the risk of bushfires.
Rising temperatures and more frequent heatwaves also pose a threat to Hawkesbury. Extreme heat can have significant impacts on human health, particularly for vulnerable populations such as the elderly and those with chronic illnesses.
While Hawkesbury is not directly on the coast, it can be indirectly affected by coastal hazards. Sea level rise and storm surges can impact the region through economic and social disruptions.
