In its post on Facebook, the Start Bay Inn said the road to the pub was now “filled with debris” and not accessible by car.
Oli Rowdon, 18, who was staying with his girlfriend in Torcross, said: “The waves coming over the houses made it feel like it was raining – our house was shaking – stuff was falling off the shelves.
“A lot of people here are worried.”
He said easterly winds overnight and damaged sea defences meant waves were “just smashing the wall”.
“The road has gone into the car park,” he said.
