Climate Hazard Breakdown for Pittwater
Flood
Pittwater faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Pittwater is moderate, with areas of bushland surrounding residential zones. Hot, dry conditions and strong winds can exacerbate the risk during bushfire season.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Pittwater experiences a high risk of heatwaves, particularly during the summer months. Rising temperatures can pose a threat to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Pittwater faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. Low-lying areas are particularly vulnerable to inundation.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Pittwater's Climate Risk Profile
Pittwater, located in New South Wales, is exposed to a range of climate-related risks. The primary concerns are flooding, bushfires, heatwaves, and coastal hazards. These risks are projected to intensify in the coming decades due to climate change.
Flooding is a significant concern due to the suburb's proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding and riverine flooding, impacting homes, businesses, and infrastructure. Sea level rise further exacerbates the risk of coastal flooding.
Bushfire risk is moderate, with areas of bushland surrounding residential zones. Hot, dry conditions and strong winds can increase the likelihood of bushfires, posing a threat to life and property. Residents should be aware of bushfire safety measures and maintain their properties accordingly.
Heatwaves are a growing concern, with rising temperatures posing a threat to vulnerable populations. The urban heat island effect can further amplify temperatures in built-up areas. It is important to stay hydrated, seek shade, and check on elderly or unwell neighbors during heatwaves.
Coastal hazards, including sea level rise and coastal erosion, pose a threat to low-lying areas. These hazards can damage infrastructure, erode beaches, and inundate properties. Long-term planning is needed to mitigate the impacts of coastal hazards.
