About Maclean's Climate Risk Profile

Maclean, located in the Clarence Valley of New South Wales, is susceptible to a range of climate-related hazards. The town's proximity to the Clarence River makes it particularly vulnerable to flooding, with heavy rainfall events capable of causing significant inundation. Climate change projections indicate an increase in the frequency and intensity of extreme rainfall, which could lead to more severe and frequent flooding in the future.

Bushfire risk is also a concern for Maclean, as the surrounding vegetation can become dry and flammable during the hotter months. Rising temperatures and prolonged periods of drought, both associated with climate change, are expected to exacerbate bushfire risk in the region. Residents should be aware of bushfire safety measures and maintain their properties to reduce the risk of fire.

Heatwaves are another significant threat to Maclean, especially for vulnerable populations such as the elderly and those with pre-existing health conditions. Climate change is projected to increase the frequency and intensity of heatwaves, potentially leading to heat stress and other health problems. It is important for residents to stay hydrated, seek shelter in cool environments, and check on their neighbors during periods of extreme heat.

While Maclean is not directly on the coast, it is still potentially vulnerable to sea level rise and coastal inundation along the Clarence River. Climate change is expected to cause sea levels to rise, which could lead to increased flooding and erosion in low-lying areas. Residents should be aware of the potential impacts of sea level rise and take steps to protect their properties.
