Climate Safety Analysis
Tumbi Umbi 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 Tumbi Umbi'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 Tumbi Umbi 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.
