Is Wellington, SA Climate Safe? 2026 Assessment
Climate Safety Score
7.2/10Climate risk is high — address assessment recommended
Key Facts
- Climate Safety
- High
- Flood
- Wellington faces a high risk of flooding due to its proximity to the Macquarie River and other waterways. Climate change is expected to increase the frequency and intensity of heavy rainfall events, exacerbating flood risk.
- Bushfire
- Wellington is located in a region with a moderate bushfire risk. Hot, dry summers and the presence of flammable vegetation contribute to the risk. Climate change is projected to increase the length and severity of the bushfire season.
- Heat
- Wellington experiences hot summers, and the risk of heatwaves is increasing due to climate change. Higher temperatures can pose a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
- Storm
- Moderate storm risk — occasional severe thunderstorms
- Postcode
- 5259
- Highest high-risk exposure
- 8.7% of land (surface flood)
Climate Safety Analysis
Wellington in South Australia has an overall climate safety rating of High. 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 Wellington's climate safety include heat, flood, 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 Wellington 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.

Wellington (postcode 5259) 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 surface flood (8.7% of land in high-risk zones), bushfire (7.8% of land in high-risk zones), extreme wind (3.5% of land in high-risk zones). Exposure is not uniform across Wellington — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
