Quality waves in the waist-to-chest high range were breaking in both directions, but the long interval in between sets led organisers to call off competition for the day.
A new call has been set for the eagerly-anticipated round of 16 which sees a man-to-man elimination.
The finals are set for Sunday, where $40,000 in prize money will be won and 6,500 ASP World Ranking points distributed amongst the competitors.
