Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.
Climate Hazard Breakdown for Brooklyn
Flood
Brooklyn faces a moderate risk of flooding due to its proximity to the Hawkesbury River and surrounding waterways. Heavy rainfall events can lead to riverine and flash flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Brooklyn has a moderate bushfire risk due to its location near bushland areas. Dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·Increased temperatures
Heat
Brooklyn is experiencing increasing average temperatures and more frequent heatwaves. This poses a risk to vulnerable populations, especially during summer.
Key drivers:
- ·Global warming
- ·Urban heat island effect
Coastal
Brooklyn is exposed to coastal risks due to its location on the Hawkesbury River. Sea level rise and storm surges can lead to inundation and erosion.
Key drivers:
- ·Sea level rise
- ·Increased storm intensity

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 Brooklyn's Climate Risk Profile
Brooklyn, located in New South Wales, is susceptible to a range of climate-related hazards. Its position near the Hawkesbury River makes it particularly vulnerable to flooding, with heavy rainfall events posing a significant threat to properties and infrastructure.
Bushfire risk is also a concern due to the surrounding bushland. Hot, dry conditions, coupled with strong winds, can create ideal conditions for bushfires to spread rapidly. Residents need to be prepared and aware of bushfire safety measures.
Rising temperatures and more frequent heatwaves are another growing concern. The urban environment can amplify the effects of heat, making it essential to take precautions during hot weather to protect vulnerable individuals.
Coastal risks, including sea level rise and storm surges, pose a threat to low-lying areas along the Hawkesbury River. These events can lead to inundation, erosion, and damage to coastal infrastructure.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Reducing greenhouse gas emissions is crucial to slowing down the rate of climate change, while local adaptation measures can help to protect communities from the impacts that are already occurring. These measures include improved flood defenses, bushfire management, heatwave preparedness plans, and coastal protection strategies.
By taking proactive steps to address climate change, Brooklyn can build resilience and protect its community from the growing risks.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
