Is Merriwagga, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.8/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Merriwagga faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from local waterways. The flat terrain contributes to slower drainage, increasing flood duration.
- Bushfire
- The area around Merriwagga is prone to bushfires, particularly during hot and dry summer months. Grasslands and sparse vegetation surrounding the town increase the risk of fire spread.
- Heat
- Merriwagga experiences high temperatures during summer, leading to heatwave conditions. Climate change is expected to exacerbate these conditions, increasing the frequency and intensity of heatwaves.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2652
- Highest high-risk exposure
- 9.6% of land (riverine flood)
Climate Safety Analysis
Merriwagga 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 Merriwagga's climate safety include heat, bushfire. 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 Merriwagga 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.
