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 Watsons Bay
Flood
Watsons Bay faces a moderate risk of flooding, primarily from heavy rainfall events and potential coastal inundation. The area's proximity to the coast and low-lying areas contribute to this risk.
Key drivers:
- ·Sea level rise
- ·Increased rainfall intensity
Bushfire
The bushfire risk in Watsons Bay is relatively low due to its urban environment and limited vegetation. However, nearby parklands could pose a threat under extreme conditions.
Key drivers:
- ·Proximity to bushland
- ·Dry vegetation
Heat
Watsons Bay is experiencing increasing heatwave frequency and intensity. Urban areas retain heat, leading to higher nighttime temperatures and increased heat stress on residents.
Key drivers:
- ·Climate change
- ·Urban heat island effect
Coastal
Watsons Bay is vulnerable to coastal erosion and inundation due to sea level rise and storm surges. The coastline is exposed, increasing the risk to properties and infrastructure.
Key drivers:
- ·Sea level rise
- ·Storm surges

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 Watsons Bay's Climate Risk Profile
Watsons Bay, a picturesque suburb in Sydney's eastern suburbs, is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and coastal inundation, exacerbated by sea level rise. Heatwaves are also becoming more frequent and intense, posing a threat to public health, especially for vulnerable populations.
The suburb's proximity to the coast makes it susceptible to coastal erosion and storm surges. Rising sea levels are expected to worsen these risks, potentially impacting properties and infrastructure along the coastline. Changes in rainfall patterns could lead to more frequent and intense flooding events, affecting low-lying areas.
Bushfire risk is relatively low compared to other parts of NSW, but nearby parklands could still pose a threat under extreme conditions. It's important for residents to maintain awareness and preparedness during the bushfire season.
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. Local adaptation measures, such as improving drainage infrastructure and implementing coastal protection measures, can help reduce the impacts of extreme weather events.
