Overall Risk Score
Hazard Breakdown
Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Alexandria
Flood
Alexandria faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, exacerbating flood risk.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Alexandria is relatively low due to its urban environment and distance from significant bushland areas. However, increased temperatures and drier conditions could slightly elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Alexandria is susceptible to heatwaves, particularly during summer. Climate change is projected to increase the frequency and intensity of heatwaves, posing a significant risk to vulnerable populations.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
Alexandria faces a moderate risk from coastal hazards due to its proximity to the coast and low-lying areas. Sea level rise and storm surges could lead to increased coastal inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Alexandria's Climate Risk Profile
Alexandria, a suburb of Sydney, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding, heatwaves, and coastal inundation. Changes in rainfall patterns and rising sea levels are expected to exacerbate these risks in the coming decades.
Flooding is a significant concern due to the suburb's low-lying topography and proximity to waterways. Increased rainfall intensity, driven by climate change, will likely lead to more frequent and severe flood events. This poses a threat to property and infrastructure.
Heatwaves are another major risk, particularly for vulnerable populations such as the elderly and those with pre-existing health conditions. The urban heat island effect further amplifies the impact of heatwaves in Alexandria. Rising temperatures will increase the frequency and intensity of these events.
Coastal inundation is a growing concern due to sea level rise and increased storm surge. Low-lying areas of Alexandria are at risk of being inundated during extreme weather events. This could lead to property damage and displacement of residents.
Addressing these climate risks requires a combination of adaptation and mitigation measures. Adaptation strategies include improving drainage infrastructure, implementing heatwave early warning systems, and protecting coastal areas. Mitigation efforts focus on reducing greenhouse gas emissions to slow the pace of climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.

Frequently Asked Questions
What are the main climate change risks in Alexandria?
The main climate change risks in Alexandria are flooding, heatwaves, and coastal inundation. These risks are expected to increase in the coming decades due to changes in rainfall patterns, rising temperatures, and sea level rise.
How will climate change affect property values in Alexandria?
Properties in flood-prone areas may experience price stagnation or decline. Properties that are more resilient to climate change impacts, such as those with good drainage and insulation, may be more attractive to buyers.
What is the council doing to address climate change in Alexandria?
The City of Sydney has a climate change adaptation strategy that outlines measures to reduce greenhouse gas emissions and adapt to the impacts of climate change. These measures include improving drainage infrastructure, implementing heatwave early warning systems, and promoting green infrastructure.
How can I prepare my home for climate change impacts?
You can prepare your home for climate change impacts by improving drainage, installing insulation, planting trees, and developing an emergency plan. It is also important to stay informed about climate change risks and take steps to reduce your carbon footprint.
Where can I find more information about climate change in Alexandria?
You can find more information about climate change in Alexandria on the City of Sydney website, the NSW Department of Planning and Environment website, and the CSIRO website.
