About Halekulani's Climate Risk Profile

Halekulani, located on the Central Coast of New South Wales, is vulnerable to a range of climate-related hazards. Its proximity to Lake Munmorah and the coast increases its exposure to flooding and coastal erosion. Rising temperatures and drier conditions also elevate the risk of bushfires and heatwaves.

The risk of flooding is primarily driven by intense rainfall events and potential storm surges. Low-lying areas are particularly susceptible to inundation. Climate change is projected to increase the frequency and intensity of extreme rainfall, further exacerbating flood risk.

Bushfire risk is influenced by the presence of nearby bushland and the increasing frequency of hot, dry conditions. Higher temperatures and reduced rainfall can lead to drier vegetation, increasing the likelihood of fire ignition and spread. Residents should maintain their properties to reduce fuel loads and be prepared for potential evacuations.

Heatwaves are becoming more frequent and intense, posing a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. Urban areas may experience a greater heat island effect, further amplifying temperatures. It is important to stay hydrated, seek shade, and take precautions during periods of extreme heat.

Coastal hazards, including sea level rise and storm surges, can lead to erosion and inundation of low-lying coastal areas. These hazards can damage infrastructure, property, and natural ecosystems. Planning for coastal adaptation is essential to protect communities and assets.
