Is Mascot, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- 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.
- 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.
- 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.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2020
- Highest high-risk exposure
- 6.2% of land (coastal inundation)
Climate Safety Analysis
Mascot in New South Wales has an overall climate safety rating of Medium. This multi-hazard assessment combines flood, bushfire, heat, coastal, and storm risk data with climate projections to 2050 from CSIRO and the Bureau of Meteorology.
Key factors affecting Mascot's climate safety include heat, flood, coastal. Each hazard is assessed independently and combined for an overall picture. Australia has warmed by approximately 1.5 °C since 1910, with flow-on effects to fire weather, extreme rainfall, and heatwave frequency.
Climate safety for property in Mascot is not uniform — it varies by address. Factors such as elevation, distance to waterways, proximity to bushland, and local drainage all influence actual risk at a specific property. Two nearby properties can have materially different risk profiles.
For a complete property-specific climate safety report for Mascot including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Mascot (postcode 2020) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are coastal inundation (6.2% of land in high-risk zones), surface flood (5.8% of land in high-risk zones), bushfire (5.1% of land in high-risk zones). Exposure is not uniform across Mascot — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Which climate hazard poses the biggest risk in Mascot?
The dominant hazard for Mascot depends on geography and local environment. Proximity to waterways elevates flood risk, while proximity to bushland increases bushfire risk. ClimateNest's multi-hazard analysis identifies the highest-risk hazards for any specific address.
How does Mascot compare to nearby suburbs for climate safety?
Nearby suburbs may have different climate risk profiles depending on elevation, vegetation cover, drainage patterns, and land use. ClimateNest allows comparison of climate safety scores across New South Wales suburbs.
Should I be concerned about buying property in Mascot?
Climate risk should be one factor in your decision, alongside price, location, and amenity. An informed buyer understands the specific risks at a property address and factors insurance costs and climate projections into their assessment of long-term value.
What climate projections should I know for Mascot?
Key projections for New South Wales from CSIRO include increased average temperatures, more frequent hot days, changes in rainfall seasonality, longer fire seasons, and potential increases in extreme rainfall intensity. These trends inform the long-term outlook for Mascot.
What share of Mascot is exposed to high coastal inundation risk?
ClimateNest's hazard overlay maps 6.2% of Mascot in high-risk zones for coastal inundation, with a further 64.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
