Learn moreAbout Mackay's Climate Risk Profile
Mackay's climate is characterized by hot, humid summers and mild, dry winters. The region is susceptible to cyclones, heavy rainfall, and heatwaves, all of which are expected to become more frequent and intense due to climate change.
Flooding is a major concern in Mackay, with the Pioneer River and other waterways posing a significant risk. Sea level rise and storm surges also threaten coastal areas, potentially leading to erosion and inundation.
Rising temperatures and increased humidity will exacerbate heat stress, particularly for vulnerable populations. Bushfire risk is relatively lower but still present, especially in areas near bushland.
Adapting to these changes will require a combination of infrastructure improvements, land-use planning, and community awareness initiatives. Residents should stay informed about potential risks and take steps to protect their homes and families.
