Hazard Breakdown
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 Chatham Valley
Flood
Chatham Valley faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The risk of bushfires in Chatham Valley is moderate, influenced by surrounding vegetation and dry conditions during the fire season. Changes in temperature and rainfall patterns can exacerbate this risk.
Key drivers:
- ·Increased temperatures
- ·Drier conditions
Heat
Chatham Valley is likely to experience more frequent and intense heatwaves. Higher average temperatures can pose health risks, especially for vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Chatham Valley is not directly exposed to coastal hazards. The risk from coastal inundation and erosion is minimal.
Key drivers:
- ·Sea level rise

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 Chatham Valley's Climate Risk Profile
Chatham Valley, NSW, is projected to experience increasing climate-related challenges in the coming decades. The primary risks include more frequent and intense heatwaves, increased flooding due to extreme rainfall events, and a moderate risk of bushfires.
The risk of flooding is expected to increase due to climate change, with more intense rainfall events predicted. This can lead to flash flooding and riverine flooding, impacting properties and infrastructure.
Heatwaves are also expected to become more frequent and intense, posing health risks to vulnerable populations. The urban heat island effect may exacerbate these risks.
While the coastal risk is low, the suburb should still consider broader regional impacts of coastal erosion and inundation.
Residents and property owners should take proactive measures to adapt to these changing conditions, including improving drainage, implementing bushfire protection measures, and preparing for heatwaves.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
