Greater Manchester Police have put out a warning to the public about open water swimming as temperatures soar.

With highs of 22 degrees reached in Bolton today, many people will want to jump into the water, but Bolton West officers have warned people of doing this.

A spokesman for GMP said: "Jumping into open water can be fatal.

"Cold water shock kills and you don’t know what’s lurking beneath the surface."

Police also advised people on what to do to help others if they are in difficulty in water.

A spokesman said: "If you get into difficulty in the water, float to live.

"Tilt your head back with ears submerged.

"Relax and try to control your breathing.

"Move your hands to help you stay afloat.

"Once you are over the initial shock, call for help or swim to safety."

Lee Heard, Charity Director at the Royal Life Saving Society UK (RLSS UK), has now offered tips on staying safe whilst wild swimming this summer.

Lee Heard advises: “If swimmers are aware of the potential risks and dangers then this enables them to do a risk assessment before entering the water.

“We always recommend going swimming with a friend and wearing appropriate clothing such as a wetsuit, a tow float and a brightly coloured swimming hat."
