About Kanwal's Climate Risk Profile

Kanwal, located on the Central Coast of New South Wales, is susceptible to a range of climate-related hazards. The suburb's proximity to Lake Munmorah increases its vulnerability to flooding, particularly during periods of heavy rainfall. Climate change is projected to intensify rainfall events, leading to more frequent and severe flooding in the future.

Bushfire risk is also a concern in Kanwal, with some areas bordering bushland. Hot, dry conditions and strong winds can create ideal conditions for bushfires to spread rapidly. Residents should be aware of bushfire safety measures and have a plan in place in case of an emergency.

Heatwaves are becoming more frequent and intense in Kanwal, posing a significant risk to vulnerable populations, such as the elderly and those with chronic health conditions. Rising temperatures can lead to heat stress, dehydration, and other health problems. It is important to stay cool and hydrated during heatwaves.

Coastal hazards, such as sea level rise and storm surges, also pose a threat to Kanwal. Low-lying areas along the lakefront are particularly vulnerable to inundation. Climate change is expected to accelerate sea level rise, increasing the risk of coastal erosion and flooding.
