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 Crows Nest
Flood
Crows Nest faces a moderate risk of flooding, primarily from heavy rainfall events and potential stormwater runoff. The area's topography and existing drainage infrastructure contribute to this risk.
Key drivers:
- ·Heavy rainfall
- ·Stormwater runoff
Bushfire
The bushfire risk in Crows Nest is relatively low due to its urban environment and distance from large bushland areas. However, ember attack from distant fires remains a potential concern.
Key drivers:
- ·Ember attack
- ·Dry vegetation in surrounding areas
Heat
Crows Nest experiences a high heat risk, particularly during summer heatwaves. The urban heat island effect exacerbates this risk, leading to higher temperatures than surrounding areas.
Key drivers:
- ·Urban heat island effect
- ·Heatwaves
Coastal
Crows Nest has a low coastal risk due to its distance from the immediate coastline. Sea level rise and coastal erosion are not direct threats to the suburb.
Key drivers:
- ·Distance from coast

What This Means for Property Owners
Insurance Outlook
Insurance premiums may increase due to increased flood and heat risks.
Price Impact
Properties in areas prone to flooding or heat stress may experience a slight decrease in value.
Buyer Checklist
- 1.Check flood history of the property.
- 2.Assess the property's vulnerability to heat stress.
- 3.Ensure adequate insurance coverage.
- 4.Consider energy efficiency measures.
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 Crows Nest's Climate Risk Profile
Crows Nest, located in North Sydney, is primarily at risk from increased heat and potential flooding due to climate change. The urban environment contributes to the urban heat island effect, making the suburb particularly vulnerable during heatwaves. Residents should take precautions during these events to stay cool and hydrated.
Flooding is another concern, with heavy rainfall events posing a risk to properties and infrastructure. Improved drainage and stormwater management are essential to mitigate this risk. The local council is responsible for maintaining and upgrading these systems.
Bushfire risk is relatively low due to the suburb's urban nature, but ember attack remains a possibility. Residents should maintain their properties to reduce potential fuel sources.
Coastal risks are minimal due to Crows Nest's distance from the coast. However, broader climate change impacts, such as extreme weather events, could still affect the suburb. Long-term planning should consider these potential impacts to ensure the community's resilience.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
