Top Barbadian surfer Chelsea Tuach is in line for bigger pay days.
The World Surf League has decided to give equal prize money to male and female competitors.
The changes will start from next year.
The WSL becomes the first US-based global sports league to achieve prize money equality.
WSL chief executive Sophie Goldschmidt, who was formerly the chief commercial and marketing director with the Rugby Football Union, said she wants the sport to lead the way in pushing for equality.
Earlier this year the WSL was criticised over the disparity in prize money between the male and female winners of a junior surfing tournament in South Africa.
Last year, a study found that 35 out of 55 sports, whose governing bodies responded, paid equal amounts to men and women.
Surfing, which is one of the world's fastest-growing sports, will be part of the Olympic programme for the first time in Tokyo in 2020.
