Water Quality

What's tested here?

Water samples are taken voluntarily at this beach by the local authority from 1st June to 15th September.

Water samples do not need to be taken at this beach and may not be treated in the same way as designated bathing waters, but they are collected in the spirit of the Bathing Waters Directive.

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?

Water quality can be reduced for up to 72 hours after heavy rain. Look out for temporary signs at the beach and on our website.

Annual classification

2015 Excellent

What’s does this mean?

At the end of every bathing season the water quality is classified as either-

Excellent – the highest classification meaning the water is cleanest
Good – generally good water quality
Sufficient – meets minimum standards
Poor – You are advised not to swim. The beach will stay open and an action plan should be in place to improve the water quality.

These new European standards are based on the latest health advice and are roughly twice as tough as the old ones. They use the latest four years of data, rather than a single year. Find out how they compare.

Beach Cleans

We need you!

Our volunteers have been surveying rubbish on  UK beaches for over 20 years. In that time shoreline litter had more than doubled and plastic has gone up by 180%!

MCS beach cleans are run all year round All year round Beach Clean events with our flagship event 'Great British Beach Clean' Great British Beach Clean - 18th to 21st Sept in September.

Volunteers record the litter they find - we use this information to help Governments and industry understand how to stop the rubbish getting there in the first place. We also promote behaviour change among the public using the data collected.
