Climate Hazard Breakdown for Mollymook
Flood
Mollymook faces a moderate risk of flooding due to its proximity to the coast and local waterways. Intense rainfall events can lead to flash flooding and riverine flooding.
Key drivers:
- ·Increased rainfall intensity
- ·Sea level rise
Bushfire
Bushfire risk in Mollymook is moderate, with areas of bushland surrounding the suburb. Hot, dry conditions and strong winds can increase the likelihood of bushfires.
Key drivers:
- ·Dry vegetation
- ·High temperatures
Heat
Mollymook is experiencing increasing heatwaves and higher average temperatures, particularly during summer. This poses a risk to vulnerable populations.
Key drivers:
- ·Rising global temperatures
- ·Urban heat island effect
Coastal
Coastal erosion and sea level rise pose a moderate threat to Mollymook's coastline. Properties close to the beach 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 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.
