Overall Risk Score
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 Cogra Bay
Flood
Cogra Bay faces a moderate risk of flooding, primarily from heavy rainfall and potential stormwater runoff. The risk is exacerbated by its proximity to waterways and low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The bushfire risk in Cogra Bay is moderate due to the presence of nearby bushland. While not immediately adjacent to dense forests, ember attacks and spot fires remain a concern during dry periods.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Cogra Bay is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, particularly the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Cogra Bay faces a moderate risk from coastal hazards, including sea level rise and potential erosion. The low-lying areas are particularly vulnerable to inundation during storm surges.
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 Cogra Bay's Climate Risk Profile
Cogra Bay, located in New South Wales, is susceptible to a range of climate-related risks. The suburb's proximity to waterways increases its vulnerability to flooding, while nearby bushland poses a bushfire threat. Rising temperatures are expected to lead to more frequent and intense heatwaves, impacting public health and infrastructure.
Sea level rise and increased storm intensity are key drivers of coastal hazards in Cogra Bay. Low-lying areas are at risk of inundation, and coastal erosion could threaten properties and infrastructure. Changes in rainfall patterns may also contribute to increased flood risk.
The local council is developing strategies to mitigate these risks, including improving stormwater drainage, managing vegetation, and implementing heatwave response plans. Residents can also take steps to protect their properties and prepare for extreme weather events.
Understanding the specific risks and taking appropriate adaptation measures is crucial for ensuring the long-term resilience of Cogra Bay. This includes staying informed about weather forecasts, maintaining properties, and supporting community-level initiatives to address climate change.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
