- Greenwich has a moderate risk of flooding due to its proximity to the Lane Cove River and Sydney Harbour. Several properties are located in low-lying areas that are susceptible to inundation during heavy rainfall events.
- Bushfire
- Greenwich has a relatively low risk of bushfire due to its location and urban density. However, some properties bordering parks and reserves may face a slightly elevated risk.
- Heat
- Greenwich experiences moderate heat risk, with increasing average temperatures and more frequent heatwaves projected. This can impact vulnerable populations and increase energy demand for cooling.
- Storm
- Moderate storm risk — East Coast Lows bring severe weather including hail and damaging winds

Climate Safety Analysis
Greenwich 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 Greenwich'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 Greenwich 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.
