Climate Hazard Breakdown for Narraweena
Flood
Narraweena faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development

Bushfire risk in Narraweena is moderate, with some areas bordering bushland. Dry conditions and strong winds can exacerbate the risk during bushfire season.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Narraweena experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Narraweena faces a moderate coastal risk due to sea level rise and potential for coastal erosion. This could impact properties and infrastructure near the coastline.
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 Narraweena's Climate Risk Profile
Narraweena, located on the Northern Beaches of Sydney, is susceptible to a range of climate-related hazards. Its proximity to waterways increases the risk of flooding during heavy rainfall events. The suburb also experiences moderate bushfire risk due to nearby bushland areas.
Rising temperatures and more frequent heatwaves pose a threat to vulnerable populations, particularly the elderly and those with pre-existing health conditions. Sea level rise and coastal erosion are also concerns for properties located near the coastline.
Climate change projections indicate that these risks will intensify in the coming decades. Increased rainfall intensity is expected to exacerbate flooding, while hotter and drier conditions will increase bushfire risk. Sea level rise will further threaten coastal areas.
Adapting to these changes is crucial to protect the community and infrastructure. This includes implementing flood mitigation measures, managing bushfire risk, and preparing for heatwaves. Residents should also consider the potential impacts of climate change when making property decisions.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
