Projections based on CSIRO and BOM climate modelling. Scenario: RCP8.5
| Hazard | Today | 2030 | 2050 |
|---|---|---|---|
| flood | 6.5 | 6.8(+0.3) | 7.2(+0.7) |
| bushfire | 4.0 | 4.1(+0.1) | 4.3(+0.3) |

Learn moreAbout Umina Beach's Climate Risk Profile
Umina Beach, located on the Central Coast of New South Wales, is a popular destination known for its beautiful beaches and relaxed lifestyle. However, like many coastal communities, Umina Beach faces increasing challenges from climate change.
The suburb's low-lying coastal location makes it particularly vulnerable to flooding. Intense rainfall events, combined with rising sea levels, can lead to both flash flooding and riverine flooding, impacting homes, businesses, and infrastructure. The risk of coastal erosion also poses a threat to the coastline and properties along the beachfront.
Rising temperatures and more frequent heatwaves are another significant concern for Umina Beach. These extreme heat events can put a strain on the community's resources and pose health risks, especially for vulnerable populations. The urban heat island effect, caused by the concentration of buildings and paved surfaces, can further exacerbate these impacts.
Bushfire risk is also present due to the proximity of bushland areas. While not as immediate a threat as flooding or heatwaves, the potential for bushfires to impact the community should not be ignored. Residents need to be aware of bushfire safety measures and prepared to evacuate if necessary.
Addressing these climate challenges requires a coordinated effort from residents, local government, and other stakeholders. By taking proactive steps to adapt to climate change, Umina Beach can protect its community, economy, and environment for future generations.
