Weston-super-Mare, a popular Somerset seaside resort famous for its amusement arcade, donkey rides, and expansive sandy beaches, may be largely underwater by 2050 due to rising sea levels. According to recent research using Climate Central’s projection tool, which models potential UK flood zones up to 2150, this beloved town is set to become one of many coastal communities affected by climate change within the next 25 years.
The projections reveal that several neighboring coastal towns along Somerset’s shoreline, including Brean, Burnham-on-Sea, and Highbridge, as well as parts of Portishead, Clevedon, and Minehead, are also vulnerable to submersion. Even London faces challenges, with the River Thames potentially breaching its banks and causing significant flooding.
Further risks extend to Dorset’s Poole, the world’s second largest natural harbor, where the iconic seafront railway station is expected to be claimed by the sea. Portsmouth, a low-lying island city, could lose most of its landmass to the encroaching tides, leaving only a narrow strip intact by mid-century.

Along the southern coast, East and West Wittering’s stunning beaches in Chichester will also feel the impact of rising seas. These areas, popular for their scenic views and visitor appeal, will see miles of sandy shores swallowed by water. Eastbourne in East Sussex, increasingly favored as a summer day trip destination from London, is predicted to experience substantial sea-level rise, with floodwaters stretching as far inland as Herstmonceux Castle.
In response to these threats, many coastal communities are investing in sea walls—robust but costly defenses that require ongoing maintenance. Other strategies include restoring natural barriers such as salt marshes and wetlands, which help absorb wave energy. Additionally, reintroducing beavers to regions like Cornwall, Devon, and Dorset is gaining traction; these animals build dams that naturally mitigate flooding effects inland.
The forecast is a stark reminder of the urgent need for climate resilience and adaptive measures to protect the UK’s vulnerable coastal towns and preserve their unique heritage and economies for future generations.
