Star Australian surf trio Tyler Wright, Stephanie Gilmore and Molly Picklum will have to wait to hit the water at Jeffreys Bay in South Africa with the World Surf League (WSL) event called off for the day.
An on-shore wind that developed late in the men's first round on the opening day of competition has continued while the swell has dropped.
World No.2 Wright reached the final at J-Bay last year, downing Gilmore in the semi-finals before she fell to Brazilian Tatiana Weston-Webb in the Corona Open title showdown.
Reigning world champion Gilmore is looking for a big result to try to break into the top five, who will compete in the WSL Finals, where she will try to add a ninth title.
She currently sits sixth in the standings while young gun Picklum is ranked fourth.
The men's opening round at Supertubes got underway on Thursday however none of the six Australian surfers, including defending champion Ethan Ewing, managed to win their heat to avoid the elimination round.
The Queenslander was beaten in a patient performance by Indonesia's Rio Waida, who won the heat with just two waves and a combined score of 14.10
Ewing will take on South African wildcard Adin Masencamp in the elimination round.
West Australian Jack Robinson finished runner-up to Ewing last year but is still looking to regain his best form after his season was interrupted by a knee injury, dropping him to eighth in the rankings.
He's still within reach of making the Finals for the second consecutive year.
Surfing in the last heat of the day Robinson was a distant third, with Italian Leonardo Fioravanti the victor.
Robinson will next face 11-time world champion Kelly Slater.
World No.2 American Griffin Colapinto dominated his heat, scoring 8.50 with a massive air to send Queensland's Liam O'Brien and Slater into the sudden-death round.
Sydney's Connor O'Leary posted a strong score of 13.53 but was pipped by Yago Dora, who landed a gob-smacking backhand rotation that scored 9.27.
O'Brien has a tough match-up with Japan's Kanoa Igarashi while O'Leary is up against countryman Callum Robson.
Top-ranked Filipe Toledo won his heat and is among the favourites in an event he won in 2017 and 2018.
