Grahamstown is likely to experience more frequent and intense heatwaves. This poses a significant risk to vulnerable populations.
Key drivers:
- ·Increased greenhouse gas emissions
- ·Urban heat island effect
Coastal
As a coastal suburb, Grahamstown is exposed to the impacts of sea level rise and coastal erosion. These factors could lead to inundation of low-lying areas and damage to infrastructure.

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 Grahamstown's Climate Risk Profile
Grahamstown, NSW, is increasingly vulnerable to the impacts of climate change. The suburb's location makes it susceptible to a range of hazards, including flooding, bushfires, heatwaves, and coastal erosion.
Rising sea levels and increased rainfall intensity are expected to exacerbate flood risks, particularly in low-lying areas. The potential for more frequent and intense bushfires is also a concern, driven by hotter, drier conditions. Heatwaves pose a significant threat to public health, especially for vulnerable populations such as the elderly and those with pre-existing medical conditions.
Coastal erosion and storm surges could lead to inundation of coastal properties and damage to infrastructure. These changes necessitate proactive adaptation measures to protect the community and its assets.
Understanding these risks and implementing appropriate strategies is crucial for ensuring the long-term resilience of Grahamstown.
