Climate Safety Score
3.2Considered climate-safe overall
Key Facts
- Climate Safety
- Low
- Flood
- Legana faces a moderate risk of flooding due to its proximity to the Tamar River and low-lying areas. Climate change is expected to increase rainfall intensity, potentially leading to more frequent and severe flood events.
- Bushfire
- The risk of bushfires in Legana is relatively low compared to other regions in Tasmania. However, drier conditions and higher temperatures associated with climate change could increase the risk in the future.
- Heat
- Legana experiences moderate heat risk, with average maximum temperatures in January around 24°C. Climate change is projected to increase the frequency and intensity of heatwaves, potentially impacting vulnerable populations.
- Storm
- Moderate storm risk — westerly wind storms and occasional severe weather
- Postcode
- 7277
Climate Safety Analysis
Legana in Tasmania has an overall climate safety rating of Low. 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 Legana's climate safety include multiple climate hazards. 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 Legana 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 Legana including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Legana. An address-level check is what tells you about a specific property before you buy, sell or insure it.

Frequently Asked Questions
Is Legana safe from climate change?
No location in Australia is entirely immune to climate change impacts. Legana has an overall Low 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 Legana?
The dominant hazard for Legana 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 Legana 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 Tasmania suburbs.
Should I be concerned about buying property in Legana?
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 Legana?
Key projections for Tasmania 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 Legana.
