Climate Hazard Breakdown for Mona Vale
Flood
Mona Vale faces a moderate risk of flooding, primarily from heavy rainfall and coastal inundation. Areas near Narrabeen Lagoon and low-lying coastal regions are particularly vulnerable.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Mona Vale is moderate due to its proximity to Garigal National Park and other bushland areas. Hot, dry summers and strong winds can exacerbate the risk.
Key drivers:
- ·Climate change leading to hotter, drier conditions
- ·Accumulation of dry vegetation
Heat
Mona Vale experiences a high risk of heatwaves, particularly during the summer months. Increased temperatures can pose a threat to vulnerable populations.
Key drivers:
- ·Climate change leading to higher average temperatures
- ·Urban heat island effect
Coastal
Mona Vale faces a moderate risk from coastal hazards, including sea level rise, coastal erosion, and storm surges. Low-lying coastal areas and beaches are particularly vulnerable.
Key drivers:
- ·Sea level rise
- ·Increased frequency and intensity of storms

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 Mona Vale's Climate Risk Profile
Mona Vale, located on the Northern Beaches of Sydney, is increasingly exposed to climate change impacts. The suburb's coastal location makes it vulnerable to sea level rise and coastal erosion, while its proximity to bushland increases the risk of bushfires. Rising temperatures and more frequent heatwaves pose a significant threat to public health, especially for vulnerable populations.
Flooding is another concern for Mona Vale, with heavy rainfall events and potential for coastal inundation impacting low-lying areas. The Northern Beaches Council is working to manage these risks through various strategies, but individual preparedness is crucial.
Climate change projections indicate that these risks will intensify in the coming decades. Residents can expect more frequent and severe heatwaves, increased bushfire danger, and greater coastal hazards. Adapting to these changes will require a combination of individual actions, community initiatives, and government policies.
Understanding the specific risks and taking proactive steps can help protect homes, businesses, and the community from the impacts of climate change. This includes preparing for extreme weather events, reducing greenhouse gas emissions, and advocating for climate-resilient infrastructure.
