Climate Hazard Breakdown for Calga
Flood
Calga faces a moderate risk of flooding, primarily from heavy rainfall events and local creek overflows. The risk is influenced by the area's topography and drainage infrastructure.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Calga has a high bushfire risk due to its proximity to extensive bushland. Hot, dry conditions and strong winds exacerbate the risk during the bushfire season.
Key drivers:
- ·Climate change
- ·Dry vegetation
Heat
Calga experiences moderate heat risk, with increasing average temperatures and more frequent heatwave events projected. This poses a risk to vulnerable populations.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Calga has a very low coastal risk due to its inland location. Sea level rise and coastal erosion are not significant threats to this suburb.
Key drivers:
- ·Distance from coast

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 Calga's Climate Risk Profile
Calga, located in New South Wales, is exposed to a range of climate-related risks. The most significant threat is bushfire, given the suburb's proximity to dense bushland. Hot, dry conditions during the summer months create a high-risk environment, and residents should maintain awareness and preparedness during the bushfire season.
Flooding is another concern for Calga, particularly during periods of heavy rainfall. Local creeks and waterways can overflow, impacting properties and infrastructure. Effective drainage and flood mitigation measures are essential to minimize the impact of these events.
Heatwaves are becoming more frequent and intense, posing a risk to vulnerable populations, including the elderly and those with pre-existing health conditions. Residents should take precautions during heatwaves, such as staying hydrated and seeking cooler environments.
While coastal risks are minimal due to Calga's inland location, the broader impacts of climate change, such as disruptions to supply chains and increased insurance costs, may still affect the community. Adapting to these changes requires a proactive approach and community-wide collaboration.
