Learn moreAbout Mollymook's Climate Risk Profile
Mollymook, a coastal suburb in New South Wales, is increasingly vulnerable to the impacts of climate change. The region is exposed to a range of hazards, including flooding, bushfires, heatwaves, and coastal erosion. These risks are projected to intensify in the coming decades due to rising global temperatures and changing weather patterns.
Flooding is a significant concern for Mollymook, with both riverine and coastal flooding posing a threat. Intense rainfall events can overwhelm local waterways, leading to flash flooding and property damage. Sea level rise is also increasing the risk of coastal inundation, particularly during high tides and storm surges.
Bushfires are another major hazard in the region, with areas of bushland surrounding the suburb. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Residents need to be prepared for bushfire season and take steps to protect their properties.
Heatwaves are becoming more frequent and intense in Mollymook, posing a risk to vulnerable populations, such as the elderly and those with chronic health conditions. Rising average temperatures are also contributing to increased heat stress and reduced comfort levels.
Coastal erosion is an ongoing issue for Mollymook, with the coastline constantly changing due to wave action and sea level rise. Properties close to the beach are particularly vulnerable to erosion and inundation. Long-term planning is needed to manage coastal risks and protect valuable assets.
