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 Warners Bay
Flood
Warners Bay faces a moderate risk of flooding due to its proximity to Lake Macquarie and local waterways. Intense rainfall events can lead to stormwater runoff and potential inundation of low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Urban development
Bushfire
The bushfire risk in Warners Bay is relatively low compared to other areas in NSW, but still present due to nearby bushland. Dry conditions and strong winds can increase the potential for bushfires.
Key drivers:
- ·Dry vegetation
- ·Increased temperatures
Heat
Warners Bay is expected to experience more frequent and intense heatwaves in the future. 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
Warners Bay faces a moderate risk from coastal hazards due to its location on Lake Macquarie. Sea level rise and increased storm intensity could lead to erosion and inundation of coastal areas.
Key drivers:
- ·Sea level rise
- ·Increased 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 Warners Bay's Climate Risk Profile
Warners Bay, situated on the shores of Lake Macquarie, is a vibrant suburb with a mix of residential, commercial, and recreational areas. The suburb's proximity to the lake makes it susceptible to flooding from heavy rainfall and rising water levels. Climate change is expected to exacerbate these risks, with more intense rainfall events and sea level rise.
Bushfire risk is present due to the surrounding bushland, although it is generally lower compared to other regions in NSW. However, dry conditions and strong winds can increase the potential for bushfires, requiring residents to maintain their properties and be aware of fire safety.
Heatwaves are becoming more frequent and intense in Warners Bay, posing a significant health risk to vulnerable populations. The urban environment can amplify the effects of heat, making it essential to have strategies for staying cool during hot weather.
Coastal hazards, such as erosion and inundation, are also a concern for Warners Bay due to its location on Lake Macquarie. Sea level rise and increased storm intensity could lead to damage to property and infrastructure along the shoreline. Adaptation measures are needed to protect the suburb from these risks.
