The River Thames is a hot spot for activity, particularly during the hot summer months.

As great as it can be for cooling off, it is important to remember that the Thames is a dangerous river - its strong current,  houseboats and debris can all cause serious risk to life.

Water safety event

At this event, members of the London Fire Brigade and National Lifeboat Institution will be giving life-saving advice for how you can stay safe in the water. 

You will also have the opportunity to try out paddling with the Hampton Canoe Club.

Event details:

  • Date: Saturday 15 June
  • Time: 12 noon to 3pm
  • Location: Bell Hill, Hampton, TW12 2EA

Know the risks

Swimming in rivers is very different to a pool. In addition to strong currents, the cold-water temperature can easily shock, limit ability to breathe and can make you tired very quickly.

Before getting in, check to make sure you are able to get out again. Steep and slippery banks can make it hard to get out and if you are tired you can get into difficulty.

Don’t swim alone - it is better to go near the water with a friend or family member and stay visible to avoid unnecessary risks.

You never know what is beneath the surface. Hazards include rocks, broken glass, bikes, needles and pollution in the water.

Never jump from height – particularly from Richmond’s bridges. The water beneath can be very shallow and there are hidden dangers. Your body can also go into shock on contact with cold water.

Alcohol or drugs are a lethal cocktail when swimming. They can limit your ability to swim, lower your inhibitions and increase the chance of taking dangerous risks.

At times of flood, never enter the water.

Cold water shock

When in cold water (anything below 15°C), your body can go into cold water shock. If this happens, you lose control of your breathing and movement. Cold water shock also causes your heart rate and blood pressure to quickly increase, which can lead to cardiac arrest.

The average sea temperature around the UK and Ireland is just 12°C. Inland waters like lakes, rivers, lochs and reservoirs can be colder – even in the hot summer months. 

Remember, if you find yourself in difficulty in the water, Float to Live.

Float to Live

If you found yourself struggling or entered the water unexpectedly, your instincts would tell you to swim hard. But cold water shock could make you gasp uncontrollably. This could cause you to breathe in water and drown.

The RNLI has five simple steps that could save your life if you get into difficulties in the water:

  1. If you’re struggling in the water, fight the urge to thrash around
  2. Lean back extending your arms and legs
  3. Gently move your limbs to help you float if necessary
  4. Float until you can control your breathing
  5. Then call 999, call out for help or swim to safety

Prams and wheelchairs

If you are using a pram or a wheelchair near any waterway, make sure you put the brakes on when stationary. This will reduce the chance of any accidents.

If you see someone in trouble

Raise the alarm – call 999 and ask for the Coastguard or the London Fire Brigade.

Throw them a line – look out for an emergency throw bag stationed around the river. If you are going to be swimming in the river, learn how to use it. If you can’t spot one, throw them something that floats or something to hold onto.

Stay safe – do not enter the water yourself.
