Climate Hazard Breakdown for Willoughby
Flood
Willoughby faces a moderate risk of flooding due to its proximity to waterways and varying elevations. Intense rainfall events can lead to flash flooding, particularly in low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urbanisation
Bushfire
Bushfire risk in Willoughby is moderate, with some areas bordering bushland. Hot, dry conditions and strong winds can elevate the risk during the bushfire season.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Willoughby experiences a moderate risk from heatwaves, with increasing average temperatures. Vulnerable populations, such as the elderly, are particularly at risk during extreme heat events.
Key drivers:
- ·Rising average temperatures
- ·Urban heat island effect
Coastal
Willoughby has a low coastal risk due to its distance from the immediate coastline. Sea level rise and coastal erosion are not significant concerns for this suburb.

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 Willoughby's Climate Risk Profile
Willoughby, located in the lower North Shore of Sydney, is exposed to a range of climate-related risks. The primary concerns are flooding due to increased rainfall intensity and heatwaves resulting from rising average temperatures. Bushfire risk is also a factor, particularly for properties bordering bushland areas.
The risk of flooding is driven by the suburb's proximity to waterways and varying elevations. Intense rainfall events can overwhelm drainage systems, leading to flash flooding in low-lying areas. Climate change is projected to increase the frequency and intensity of these rainfall events, further elevating the flood risk.
Heatwaves pose a significant threat to vulnerable populations in Willoughby, such as the elderly and those with pre-existing health conditions. Rising average temperatures and the urban heat island effect contribute to this risk. Climate change is expected to lead to more frequent and prolonged heatwaves, increasing the strain on emergency services and healthcare systems.
While Willoughby is not directly on the coast, it is still important to consider the broader impacts of climate change. Changes in weather patterns and increased extreme weather events can affect the suburb's infrastructure and economy. Residents should take steps to prepare for these potential impacts and adapt to a changing climate.
