Competition in the World Surf League's Rio Pro has been put on hold until at least Wednesday with a big swell in the forecast.
After one day of competition, surfers now have two days off with waves of up to three metres expected to arrive at Brazil's Praia de Itauna break midweek.
"The surf has dropped quite considerably since yesterday, it's only two to three feet and with very slow sets," said WSL spokesman Renato Hickel.
"Some good ones when they do come, but not consistent enough to put an important round in the water.
"We know we have a big swell on the way, expecting six to 10 foot waves on Wednesday and that's when we'll have our next call."
The women's draw is up to the quarter-final stage, with Molly Picklum and Tyler Wright still flying the Australian flag.
World No.3 Picklum, who can take over the rankings lead with another heat win, next faces Arena Rodriguez, who is competing in her first Championship Tour event.
The 19-year-old from Peru produced the biggest shock result of the event by eliminating current world No.1 Gabriela Bryan.
Picklum is the only surfer in the world's top five to advance to the quarter-finals.
When competition resumes two-time world champion Wright will take on local hope Luana Silva for a place in the semi-finals.
Australia's two leading male surfers Jack Robinson and Ethan Ewing must contest the elimination round.
Robinson will take on Indonesian star Rio Waida while Ewing has drawn exciting young Frenchman Marco Mignot.
With two more competitions before the Finals-bound top five head to Cloudbreak in Fiji to decide the world champion, Ewing is ranked six and Robinson seven.
Sydney rookie Joel Vaughan, competing on his first year on tour, is already safely through to the round of 16 after convincingly winning his heat against Japan's third-ranked Kanoa Igarashi and Brazilan Alejo Muniz.
