NAZARE, Portugal - Brazilian surfer Lucas Chianca won the 2023 Nazare Big Wave Challenge on Monday as 10.67-meter-plus waves hit the Portuguese coast with extreme weather wreaking havoc around Europe.

After waiting for almost two months for a big swell in what has been a quiet season in Nazare, the competition started with 7.62-meter waves on Monday morning and wrapped up with 10.67-meter-plus walls late in the afternoon, but never reached the potential 15.24-meter swell that had been forecast.

Portugal's Nazare boasts arguably the biggest ridable waves in the world, magnified by an underwater canyon 5 km deep which ends where the North Atlantic meets the shoreline near the former fishing village.

Hawaiian Garrett McNamara put Nazare on the map in 2011 when he set a then world record for the biggest wave ever surfed at 23.77 meters.

Brazilian Rodrigo Koxa bettered McNamara's mark in 2017, also at Nazare, and German Sebastian Steudtner broke the record again there in 2020, surfing an 26.21-meter wave.

On Monday, it was not the biggest Nazare can deliver, but Chianca put on a show with plenty of walls to work on and caught the best wave of the day, scoring 7.83 to become champion.

He also won the Best Team Performance alongside compatriot Pedro Scooby. Maya Gabeira beat Michelle des Bouillons to win the Women's Best Performance in another all-Brazilian showdown.

The competition is over but more waves are expected as extreme weather has been causing travel disruptions and power outages around Europe.

Hundreds of flights were delayed or cancelled in many European countries over the last few days, while snowstorms caused havoc on the roads in Spain and Austria.
