Is Narran Lake, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.5/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Narran Lake is susceptible to flooding due to its low-lying topography and proximity to the Narran River. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- The area around Narran Lake has some bushfire risk due to surrounding vegetation. Hotter, drier conditions associated with climate change may increase the likelihood of bushfires.
- Heat
- Narran Lake experiences high temperatures, particularly during summer. Climate change is projected to lead to more frequent and intense heatwaves, posing a risk to vulnerable populations.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2839
- Highest high-risk exposure
- 10.3% of land (bushfire)
Climate Safety Analysis
Narran Lake 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 Narran Lake's climate safety include heat, flood. 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 Narran Lake 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 Narran Lake including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Narran Lake (postcode 2839) 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 (10.3% of land in high-risk zones), surface flood (9.9% of land in high-risk zones), riverine flood (8.5% of land in high-risk zones). Exposure is not uniform across Narran Lake — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions
Is Narran Lake safe from climate change?
No location in Australia is entirely immune to climate change impacts. Narran Lake has an overall Medium climate risk rating. Understanding the specific hazards at your property address — not just the suburb average — provides the most reliable risk picture.
Which climate hazard poses the biggest risk in Narran Lake?
The dominant hazard for Narran Lake 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 Narran Lake 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 Narran Lake?
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 Narran Lake?
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 Narran Lake.
What share of Narran Lake is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 10.3% of Narran Lake in high-risk zones for bushfire, with a further 75.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
