Is Longueville, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Longueville is located near the Lane Cove River and Sydney Harbour, making it susceptible to flooding from heavy rainfall and storm surges. Climate change is expected to increase the intensity of rainfall events, potentially worsening flood risks.
- Bushfire
- While not immediately adjacent to large bushland areas, Longueville has some bushfire risk due to nearby reserves and potential for ember attack. Drier conditions and higher temperatures could exacerbate this risk.
- Heat
- Longueville is likely to experience more frequent and intense heatwaves due to climate change. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2066
- Highest high-risk exposure
- 13% of land (bushfire)
Climate Safety Analysis
Longueville 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 Longueville'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 Longueville 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.

Longueville (postcode 2066) 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 bushfire (13% of land in high-risk zones), surface flood (7.4% of land in high-risk zones), riverine flood (7.1% of land in high-risk zones). Exposure is not uniform across Longueville — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
