I remember my mum telling me that she lived near the Thames as a child, but wasn't allowed to swim in it. But the dog was. How come the Thames was okay for the dog to swim in but not people? She never got her answer.

The River Thames is a tidal river, meaning its water levels rise and fall with the tide. This can make swimming tricky and potentially dangerous, especially in certain sections of the river where the current is strong. The Thames is also used by a wide variety of boats, which can pose a risk to swimmers.

In the UK, swimming in natural bodies of water is generally allowed unless there are specific local laws or bylaws that prohibit it. In the case of the Thames, there are no blanket restrictions that make swimming illegal. However, the Port of London Authority (PLA), which oversees the tidal part of the Thames, strongly advises against swimming in most parts of the river due to safety concerns. This isn't a law, but it is something to take seriously.

Is it Legal to Swim in the River Thames?

Swimming in the River Thames might sound like a fun idea, especially on a hot day, but is it actually legal? The short answer is yes, it is legal to swim in the Thames. However, there are important restrictions and safety concerns to consider.

That said, organised events like the annual Henley Swim or the Serpentine Swimming Club’s events are legal and have safety measures in place, such as lifeguards and controlled environments.

Safety and Restrictions

While swimming in the Thames is legal, there are key restrictions:

  • Avoid swimming in Central London: The stretch of the river through central London is particularly dangerous due to strong currents and heavy boat traffic.
  • Follow local guidelines: Always check for any local signs or advice against swimming, as some areas might have specific rules.
  • Participate in organised events: These are generally safer options if you wish to swim in the Thames.

The PLA and other authorities may take action if they believe your swimming activity is unsafe or causing disruption. So, while you won't be breaking the law by taking a dip, it's crucial to prioritise safety and respect the river's power.
