Rio de Janeiro - Strong winds swept through Rio de Janeiro on Sunday to see all rowing events called off for the day.
South Africans were due to feature in four rowing heats, but all races were postponed at Lagoa Stadium.
Lee-Anne Persse and Kate Christowitz were due to take part in the heats of the women's pairs, Kirsten McCann and Ursula Grobler in the lightweight women's doubles sculls, James Thompson and John Smith in the lightweight men's double sculls while David Hunt, Vincent Breet, Jonathan Smith and Jake Green were the last South Africans in action the men's fours.
But persistent winds meant that organisers were forced to make a call.
A revised time slot was yet to be announced.
The winds also saw some of the tennis matches on the outside courts delayed.
