Is Whalan, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Whalan faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. The risk is expected to increase with climate change due to more intense rainfall.
- Bushfire
- Whalan has a moderate bushfire risk due to its proximity to bushland areas. Hot, dry conditions during the bushfire season can increase the likelihood of fires.
- Heat
- Whalan experiences high temperatures during summer, leading to heat stress, especially for vulnerable populations. Climate change is projected to increase the frequency and intensity of heatwaves.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2770
- Highest high-risk exposure
- 16.6% of land (bushfire)
Climate Safety Analysis
Whalan 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 Whalan'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 Whalan 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 Whalan including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Whalan (postcode 2770) 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 (16.6% of land in high-risk zones), riverine flood (12.3% of land in high-risk zones), surface flood (10.6% of land in high-risk zones). Exposure is not uniform across Whalan — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
