With warmer days on the way this summer, it’s tempting to think about cooling off in the River Thames – but there are a few important things to know before you consider a swim.
Parts of the Thames in south-west London is looked after by the Royal National Lifeboat Institution (RNLI) station in Teddington, the 5th busiest station in the UK.
To discuss staying safe this summer, Miranda Jaggers, Water Safety Officer at Teddington RNLI, shared some important reminders from her years of experience.
She said the Thames is a wonderful river, but what many people don’t realise is that, despite warm weather, the river stays cold, even in summer — and whether you enter willingly or accidentally, that water can have an extreme impact on the body.
Miranda said: “As you fall in you inhale, it’s a reflex action which you have no control over, and you can take water into your lungs.”
“So if you fall in, float on your back and extend your arms and legs, take control of your breath and call for help.”
If you ever see someone struggling in the water, people are advised to tell them to float on their back, do not enter the water yourself, and dial 999.
Miranda also emphasised the use of ‘What Three Words’, this app pinpoints your exact location, meaning the lifeboat team can reach the scene quickly.
There are also throw bag boards located along the river, and after calling 999 they can provide you with a code to unlock the lockbox and throw the rope to the person.

Miranda said: “Do not be afraid to call 999 if you get into trouble, and ask for the Coast Guard.”
However, there are still ways to enjoy the river safely. Joining a local cold water swimming group is a brilliant way to experience the river – easing into the water gradually, surrounded by people who know what they’re doing.
Alternatively you can book a space for a open water swim at Shepperton Lakes or paddle board to a pub.
With plenty of options to enjoy the Thames and local waters this summer, it’s important to stay safe and ahead RNLI advice.
