Bushfire risk in Perth CBD is relatively low due to its urban environment and limited vegetation.

Key drivers:

  • ·Proximity to bushland areas
  • ·Dry vegetation

Heat

Perth CBD experiences a high risk of heatwaves, particularly during the summer months, exacerbated by the urban heat island effect.

Key drivers:

  • ·Rising average temperatures
  • ·Increased frequency of heatwaves

Coastal

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.

About Perth CBD's Climate Risk Profile

Perth CBD, located in Western Australia, is susceptible to several climate-related risks. The suburb's proximity to the Swan River and the coast makes it vulnerable to flooding and coastal hazards. Rising temperatures and the urban heat island effect contribute to a high risk of heatwaves.

Flooding is a concern due to increased rainfall intensity and potential storm surges. Coastal erosion and sea level rise also pose a threat to infrastructure and property. While bushfire risk is relatively low, it is still a factor to consider.

Climate change projections indicate that these risks will intensify in the coming decades. Increased frequency and severity of extreme weather events are expected, impacting the livability and economic viability of Perth CBD.

Adaptation measures are crucial to mitigate these risks. These include improving drainage infrastructure, implementing heat mitigation strategies, and protecting coastal areas. Community awareness and preparedness are also essential for building resilience.
