Today's forecast

Forecasts are not available for this location.

Chesil Beach, sometimes also called Chesil Bank, is an astonishing 18 miles long. The coarse sandy beach is a tombolo, the UK’s largest, and slopes gently, connecting the Isle of Portland to the mainland and stretching from Portland to Abbotsbury and West Bay.


Fishing and fossil hunting - the cliffs are rich in ammonites and shellfish fossils. The beach is part of the Dorset and East Devon World Heritage Site - otherwise known as the Jurassic Coast. Portland Castle is nearby and there’s lots of cafes.

Wildlife and Walks

Walk along the tombolo but be warned the pebbles do make walking hard work. Visit Chesil Beach Centre which offers information and refreshments.

What's tested here?

Water samples are not taken at this beach because it has not been designated as a bathing water and there is no voluntary sampling.
Why isn't this a designated bathing water?

High levels of bacteria in the water can indicate pollution from sewage treatment works or polluted rain water draining from the land.
Where does pollution comes from and how can you help?
