Is Marulan, NSW Climate Safe? 2026 Assessment
Climate Safety Score
5.2/10Moderate climate risk — address-specific
Key Facts
- Climate Safety
- Medium
- Flood
- Marulan faces a moderate risk of flooding due to its proximity to the Wollondilly River and local creeks. Intense rainfall events can cause these waterways to overflow, impacting low-lying areas.
- Bushfire
- The area surrounding Marulan is classified as bushfire prone. Densely vegetated areas increase the risk of bushfires, particularly during hot and dry conditions.
- Heat
- Marulan experiences moderately high temperatures during summer, with potential for heatwaves. Climate change is expected to increase the frequency and intensity of heat events.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds
- Postcode
- 2579
- Highest high-risk exposure
- 17.3% of land (bushfire)
Climate Safety Analysis
Marulan 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 Marulan's climate safety include 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 Marulan 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 Marulan including address-level hazard mapping, insurance outlook, and adaptation recommendations, use the ClimateNest full analysis tool.
Marulan (postcode 2579) 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 (17.3% of land in high-risk zones), surface flood (12.8% of land in high-risk zones), riverine flood (7.9% of land in high-risk zones). Exposure is not uniform across Marulan — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
