It was almost an unofficial swimming gala in the Thames at Teddington early today.

About ten swimmers, some wearing wet suits and others not, were all equipped with bright orange swim floats, which helps visibility in the river.

Two groups of swimmers heading up stream and down stream met mid-river for a morning chat at about 8.15am and to discuss whether they were on the right side of the river!

Swimming in the river has become more popular over recent years as the river has become much cleaner but strong currents and river traffic can be hazards to inexperienced swimmers.

Over the weekend scores of sunbathers headed to the small 'beach' area near Teddington Lock footbridge to take advantage of the stunning weather.

The do's and don'ts of swimming in the Thames

Keen to give open water swimming a go? Hold on – it's not a case of putting on your costume/trunks and diving straight in.

The Amateur Swimming Association (ASA) offers these tips to get started:

You need to be a competent swimmer. Become a strong pool swimmer first then it's a fairly simple transition into open water.

If you are competent, then practice for open water swimming in the pool.

Be honest with yourself about how fond you are of fish, slimy vegetation, and insects. Yes, you can see and feel them all. This is not a chlorine-controlled pool environment.

Get into open water swimming with a friend. Swimming alone in open water is not recommended. The temperature and choppiness of the water can make things difficult.

Open water is cold — buy a wetsuit. They help insulate against the cold and keep you buoyant in open water. They are also great fun to wear.
