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 Jannali
Flood
Jannali faces a moderate risk of flooding, primarily from heavy rainfall events and potential overflow from nearby waterways. The risk is expected to increase with climate change due to more intense rainfall.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
Jannali has a moderate bushfire risk due to its proximity to bushland areas. Hot, dry conditions during the bushfire season can increase the likelihood of fire.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Jannali is likely to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with pre-existing health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Jannali faces a low to moderate risk from coastal hazards. Sea level rise and storm surges could potentially impact low-lying areas and waterways.
Key drivers:
- ·Sea level rise
- ·Storm surge

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 Jannali's Climate Risk Profile
Jannali, located in the Sutherland Shire of New South Wales, is a suburb that is increasingly vulnerable to the impacts of climate change. The primary risks include flooding from heavy rainfall and rising sea levels, as well as more frequent and intense heatwaves. Bushfire risk is also a concern due to the proximity of bushland areas.
The risk of flooding is driven by increased rainfall intensity and potential overflow from nearby waterways. Climate change is expected to exacerbate these conditions, leading to more frequent and severe flooding events. Residents and businesses should be aware of flood risks and take appropriate precautions.
Heatwaves are another significant concern for Jannali. Rising global temperatures and the urban heat island effect are contributing to more frequent and intense heatwaves, which can pose a serious risk to vulnerable populations. It is important to stay hydrated, seek shelter in cool places, and check on elderly or unwell neighbors during heatwaves.
While the coastal risk is relatively lower compared to other hazards, sea level rise and storm surges could still impact low-lying areas and waterways in Jannali. It is important to monitor coastal erosion and take steps to protect coastal infrastructure.
Addressing these climate risks requires a combination of mitigation and adaptation strategies. Mitigation involves reducing greenhouse gas emissions to slow down the rate of climate change, while adaptation involves taking steps to prepare for the impacts that are already occurring or are expected to occur in the future.
Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
