How the region's climate is projected to change
Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.
Temperature
+0.5 to 1.1°C by 2030
Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.
Rainfall
Winter rain down up to 15% by 2030
The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.
Fire weather
Harsher, magnitude uncertain
High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.
Sea level
+0.12 m by 2030
At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

Learn moreAbout Heddon Greta's Climate Risk Profile
Heddon Greta, located in the Hunter Region of New South Wales, is susceptible to several climate-related hazards. The primary concerns are flooding due to its proximity to local waterways, and increasing heatwave frequency and intensity.
The risk of flooding is expected to increase with climate change, as more intense rainfall events become more common. This could lead to property damage and disruption to local infrastructure. Residents should be aware of flood risks and take appropriate precautions.
Bushfire risk is also a factor, particularly during the dry season. The surrounding bushland can create a significant fire hazard, and hotter, drier conditions are likely to exacerbate this risk. Preparedness and awareness are crucial for mitigating potential bushfire impacts.
Heatwaves pose a significant threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. The increasing frequency and intensity of heatwaves could strain local healthcare services and impact overall quality of life.
While Heddon Greta is not directly exposed to coastal hazards, the broader impacts of climate change, such as economic disruption and displacement of populations, could indirectly affect the suburb. Proactive adaptation measures are essential to build resilience and ensure a sustainable future for Heddon Greta.
