The penultimate stop of the season will finalise the five men and five women who will compete in California from September 8 to 16 to decide the overall victors.

Defending champion Filipe Toledo of Brazil, Australia's Ethan Ewing, and Griffin Colapinto of the United States have all sealed their places.

A trio of Toledo's compatriots are in the running for fourth and fifth position as Joao Chianca, Yago Dora, and Gabriel Medina are within 7,520 points of each other.

With 10,000 ranking points going to the winner in Tahiti it is all to play for.

The top 10 men and top eight women in the season rankings will also clinch a Paris 2024 qualifying spot for their National Olympic Committee at next year's Summer Olympics.

Defending men's Olympic champion Ítalo Ferreira, also of Brazil, currently sits outside of the cut-off point in 12^th.

He is 3,330 points away from 10^th place Ryan Callinan of Australia.

In the women's event, only one place remains to go to the Finals in Lower Trestles with Americans Carissa Moore and Caroline Marks, and Australia's Tyler Wright and Molly Picklum all safely through.

The US' Lakey Peterson jumped up two places into sixth after her victory at J-Bay Pro in South Africa last month to put herself in contention.

Her compatriot Caitlin Simmers is currently fifth with two victories so far while Australian legend Stephanie Gilmore is also a threat.

Olympic champion Moore has led the rankings since winning Surf Ranch Pro in late May and currently has 57,745 points.

Taking place just under a year before surfing at Paris 2024, from July 27 to 30 next year, the event is acting as a curtain-raiser to the sport's second Olympic appearance after Tokyo 2020.

Being 9,800 miles from Paris, Teahupoʻo is a record-breaking distance between a host city and competition sub-venue.

The previous mark was set during Melbourne 1956 when the equestrian events were held approximately 9,700 miles away in Stockholm, Sweden.
