Australian surfers Ethan Ewing and Molly Picklum have had their World Surfing League ambitions put on hold at Praia de Itaúna, in Saquarema, Brazil.
Weather conditions prevented competition in the Vivo Rio Pro, stop 9 of the competition, with the rest of the event now to be completed on Sunday, local time (Monday AEST).
Spokesperson Renato Hickel said: "We woke up to improved conditions and with better size, but the wave quality still isn't up to par to resume the competition.
"However the forecast is looking really good for tomorrow."
Finals day will start with the completion of the women's quarter-finals, with Pickum already through to the last four after beating Peru's Arena Rodriguez in an earlier tie.
Another Australian, Tyler Wright, was eliminated by Brazil's Luana Silva in one of the other three already completed quarter-finals.
Ewing competes in the last of the four men's quarter-finals, taking on home hope Italo Ferreira, the defending Vivo Rio Pro event winner, in a mouth-watering match-up.
