Summer Robertson died alongside Alice Barnett, 19, from Tring in Hertfordshire when they were dragged out to sea by fierce currents near Kenton-on-Sea, a small town on the south-eastern coast of South Africa.

The tragic incident happened at around 8pm on December 4 whilst the pair enjoyed a celebratory swim with three-other British members of a team that had completed a 10-week charity adventure.

Lifeguards at a nearby surfing tournament heard their desperate cries for help and managed to save three of the five swimmers. The three survivors, two males and a woman, showed signs of near drowning symptoms and were treated by the team’s medics before being transported to hospital for observation for secondary drowning.

Summer was a former student at Sundorne School and Shrewsbury Sixth Form. She had previously worked as a sales assistant for Dunelm and was said to be working for Jaguar Landrover at the time of her death.

Paying tribute today friend Beth Hemmings wrote on Twitter: “My heart goes out to Summer Robertson’s family. Really hits home how valuable life is when something so tragic happens to someone you knew.”
