AN INTERACTIVE map has revealed what parts of Denbighshire and surrounding areas could be underwater in just seven years. 

Created by Climate Central, the interactive map shows areas threatened by sea level rise and coastal flooding by 2030. It combines the most advanced global model of coastal elevations with the latest projections for future flood levels.

Climate Central’s sea level rise and coastal flood maps are based on peer-reviewed science in leading journals. As these maps incorporate big datasets, which always include some error, these maps should be regarded as screening tools to identify places that may require deeper investigation of risk [areas that may be more at risk of sea levels rising].

Areas lower than the selected water level and with an unobstructed path to the ocean are shaded red. The maps are not based on physical storm and flood simulations and do not take into account factors such as erosion, future changes in the frequency or intensity of storms, inland flooding, or contributions from rainfall or rivers.


The map shows that Rhyl and Prestatyn will largely be underwater by 2030. Holiday parks such as Lyons Robin Holiday Park, Lyons Lido Beach and Haven Presthaven Park will all be submerged.

Abergele could also be lost along with Towyn and Kinmel Bay.

Gwrych Castle is safe and stands a distance away from water affected areas. 

Glan Clwyd Hospital in Bodelwyddan is shown just outside the red shaded area. Areas such as Dyserth and Gwaenysgor appear unaffected. St Asaph is also spared. 


Moving further along the coast and it is mainly the beaches that have disappeared as well as large areas of the North Wales Expressway and the prom. However, Llandudno appears to be a casualty with much of the town affected; The Home Front Museum, Ysgol John Bright, Asda, Venue Cymru and Mostyn Champneys Retail Park are all shaded red.

Cineworld in Llandudno Junction and Tesco also fall victim.

In Colwyn Bay, the zoo appears untouched. The rest of the town also fares well.

Rhos on Sea beach appears underwater as well as Coleg Llandrillo but the majority of the town is expected to remain unscathed.
