Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- North Tumbulgum faces a significant flood risk due to its proximity to the Tweed River. The area is susceptible to both riverine and flash flooding, which can inundate properties and disrupt infrastructure.
- Bushfire
- The bushfire risk in North Tumbulgum is moderate. While not immediately surrounded by dense bushland, the area is still vulnerable to ember attacks and potential fire spread from nearby vegetation.
- Heat
- North Tumbulgum experiences moderately high temperatures during summer, leading to potential heat stress for vulnerable populations. The frequency and intensity of heatwaves are projected to increase.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2490
- Highest high-risk exposure
- 11% of land (surface flood)
Climate Safety Analysis
North Tumbulgum 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 North Tumbulgum'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 North Tumbulgum 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.
