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 Lake Munmorah
Flood
Lake Munmorah faces a moderate risk of flooding due to its proximity to Lake Munmorah and other waterways. Intense rainfall events can lead to stormwater runoff and riverine flooding, impacting low-lying areas.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
The suburb has a moderate bushfire risk due to surrounding bushland. Hot, dry conditions and strong winds can increase the likelihood of bushfires spreading into residential areas.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Lake Munmorah is expected to experience more frequent and intense heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Lake Munmorah faces a moderate risk from coastal hazards, including sea level rise and coastal erosion. Low-lying areas near the lake are particularly vulnerable.
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 Lake Munmorah's Climate Risk Profile
Lake Munmorah, located on the Central Coast of New South Wales, is increasingly vulnerable to the impacts of climate change. Rising temperatures, changing rainfall patterns, and sea level rise pose significant challenges to the community and its infrastructure.
The risk of flooding is a major concern for Lake Munmorah. The suburb's low-lying areas near the lake are susceptible to inundation during heavy rainfall events. Climate change is expected to increase the intensity and frequency of these events, exacerbating the risk of flooding and causing damage to property.
Bushfire risk is also a factor, with surrounding bushland creating a potential hazard during hot, dry conditions. While not as severe as flooding, the risk is still present and requires careful management and preparedness.
Heatwaves are becoming more frequent and intense, posing a significant threat to public health, particularly for vulnerable populations. The urban heat island effect can further amplify these impacts, making it essential to implement strategies to mitigate heat exposure.
Sea level rise and coastal erosion are also concerns, particularly for properties located near the lake. These hazards can lead to property damage, loss of amenity, and displacement of residents.
