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.
