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 Mascot
Flood
Mascot faces a moderate risk of flooding due to its low-lying areas and proximity to waterways. Climate change is expected to increase rainfall intensity, potentially worsening flood events.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The risk of bushfire in Mascot is relatively low due to its urban environment and distance from large bushland areas. However, increased temperatures and drier conditions could elevate the risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Mascot is susceptible to heatwaves, particularly during the summer months. Climate change is projected to increase the frequency and intensity of heatwaves, posing a risk to vulnerable populations.
Key drivers:
- ·Increased temperatures
- ·Urban heat island effect
Coastal
Mascot faces a moderate risk from coastal hazards due to its proximity to Botany Bay. Sea level rise and storm surges could lead to inundation and erosion in low-lying areas.
Key drivers:
- ·Sea level rise
- ·Storm surges

What This Means for Property Owners
Insurance Outlook
Insurance premiums are likely to increase due to the rising risk of flooding and coastal inundation.
Price Impact
Properties in flood-prone areas may experience a decrease in value.
Buyer Checklist
- 1.Check flood maps and historical flood data.
- 2.Assess the property's vulnerability to coastal erosion.
- 3.Inquire about the property's energy efficiency.
- 4.Consider the potential impact of heatwaves on the property.
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 Mascot's Climate Risk Profile
Mascot, located in the inner-southern suburbs of Sydney, is exposed to a range of climate-related risks. Its low-lying topography and proximity to Botany Bay make it vulnerable to flooding and coastal inundation. The increasing frequency and intensity of heatwaves also pose a significant threat to the health and well-being of residents, especially the elderly and those with pre-existing conditions.
Climate change projections indicate that Mascot will experience more extreme weather events in the coming decades. Rainfall intensity is expected to increase, leading to a higher risk of flash flooding. Sea levels are also projected to rise, exacerbating coastal erosion and inundation. The urban heat island effect, caused by the concentration of buildings and paved surfaces, will further amplify the impact of heatwaves.
Addressing these climate risks requires a multi-faceted approach. This includes investing in flood mitigation infrastructure, such as improved drainage systems and seawalls. Implementing urban greening initiatives can help to reduce the urban heat island effect and provide shade during heatwaves. Raising community awareness about climate risks and promoting preparedness measures are also crucial.
Furthermore, reducing greenhouse gas emissions is essential to mitigate the long-term impacts of climate change. This requires transitioning to renewable energy sources, improving energy efficiency, and promoting sustainable transportation options. By taking proactive steps to adapt to and mitigate climate change, Mascot can enhance its resilience and ensure a sustainable future for its residents.
