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

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.

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.
