Impressive footage has emerged of an Australian surfer riding absolutely massive waves during a storm in Nazare, Portugal.

The video, filmed on Monday, shows Mick Corbett surfing on the monster waves, said to among the biggest of the winter so far.

The filmer later wrote online: "Today (Monday) is one of the biggest swells of the winter hit the Portuguese coast, with huge waves and storm conditions.

"The lineup was really scary, but two Australian surfers, Mick Corbertt and Jarryd Foster, decided to make a try and ride those monsters of water."
