Australian surfer Mick Fanning has regained top spot on the world rankings after winning the Hurley Pro at Trestles in California.

Fanning won the final against Brazilian Adriano de Souza, who had been in the number one spot since he won at the Margaret River event in April.

Fanning scored a combined total of 17.44 and recorded the highest scoring wave of the final with a 9.77.

Fanning was interviewed in the water straight after the win by commentator Pete Mel, who was the first person he spoke to after his near miss with a shark at an event in South Africa.

"The circumstances are a little bit different this time aren't they Mick?" Mel quipped.

"Yes they are," Fanning replied.

"I'm really stoked with this win, for number one and two to go at it in the final is great for everyone. Adriano is a champion who never gives up."

Fanning also beat current world champion Gabriel Medina in the semi-final, fellow Australian Adrian Buchan in the quarterfinal and 11-time world champion Kelly Slater earlier in the event.

"I'm stoked it all came off for this event," he said.

"I'll go home, regroup and get ready for the European leg."

Fanning employed the services of local surfer and former professional, Mike Parsons, in the lead up to the event to gain an insight to the variables of the often tricky wave.

"Mick got here a week before the competition and we worked on selecting the right board and getting a handle on the best waves to look for," Parsons said.

"He came with the hunger he's renowned for and from what I saw, he will be a threat for the rest of the year."

Earlier in the event, Hawaiian Carissa Moore beat South African, Bianca Buitendag in the final to also move back into the lead on the world tour rankings.

"This is my happy place," Moore said.

"I grew up competing here and although it can get crazy and crowded but that's all part of the experience of surfing here."

Both the men's and women's tour head to Europe for the next two events before the final leg in Hawaii.

Two other Australians, Owen Wright and Julian Wilson finished the event ranked in the top 10 on the men's tour while Sally Fitzgibbons is the highest ranked female, currently in third.

Fellow Australian Stephanie Gilmore remains unable to compete due to an injury she sustained while surfing in Margaret River.
