The Duke of Sussex has been filmed showing off his impressive surfing prowess.

Footage of Prince Harry, 40, catching a wave at a California surf school was published on social media by professional surfer Raimana Van Bastolaer.

It shows the Duke, wearing a long-sleeved top and purple shorts, expertly navigating a wave as Van Bastolaer shouts out instructions.

“In Tahiti we still call you Prince Harry but at surf ranch, we call you brother,” he wrote in the caption. “It was an honour to have you surf with me.”

The clip was filmed at a “surf ranch” in Lemoore, California, owned by surfing star Kelly Slater.

It starts with the Duke riding alongside Van Bastolaer’s jet ski before he pulls away as a wave emerges.

Van Bastolaer shouts “get up, get up!” before Prince Harry gets to his knees and then stands up on his board. After carefully finding his balance, he then surfs the wave for around a minute before it petered out.

Van Bastolaer can be heard shouting: “Yeah! Keep going! Yeah brother! Move your shoulders!” As the Duke veers away from the jet ski, he yells: “Come back to me! Come back, come back!”

The ranch, featuring a barrelling 1.8-metre artificial wave that lasts for up to 700m is said to be the first of its kind.

It is the only one to hold World Surf League accreditation, meaning it is fit to stage elite-level competitions.

The ranch promises to offer an “immersive surf lifestyle experience in the middle of farm fields in central California”, 100m from the coast.

The footage comes four years after it was claimed the Duchess of Sussex had bought her husband surfing lessons for his 36th birthday, shortly after they had moved to the US and bought their home in Montecito.

In 2012, Prince Harry and his brother, the Prince of Wales, were pictured bodyboarding on a beach in Cornwall.
