A third surfer in two days has had a close encounter with a shark on Victoria's surf coast.

Rory Angiolella​ was surfing with two friends at Thirteenth Beach on Saturday morning when a large shark hit his legs and chest with its fin as he sat in the line-up waiting for a set to come.

On Friday, a surfer was knocked off his board by a shark at nearby Bells Beach, while another surfer was bumped at Thirteenth Beach.

"Out of nowhere, something started hitting me in the chest and leg," Mr Angiolella said.
