Camp Bestival organisers have cancelled the festival due to bad weather.
After weeks of high temperatures in the UK, thunderstorms, high winds and rain caused many tents to flood.
A video showed a tent coming close to taking off and the steel perimeter fence collapsed in places.
"My husband got hit in the face with a tent before it took off into the sky like a kite," the filmer said.
"People dumped tents and camping gear to make a quick exit," she added.
The festival, held at Lulworth Castle in Dorset, was supposed to close tonight (29 July).
