The day was originally launched in 2005 by Surfrider Foundation and Surfing Magazine.

The Surfrider Foundation aims to help protect and preserve It focuses on water quality, beach access, beach and surf spot preservation, as well as sustaining marine and coastal ecosystems.

The Foundation announced ahead of the day, which falls on the third weekend in June each year, that "The Beach Belongs to Everyone" would be the theme of the 2021 event.

The theme was chosen to celebrate "the joy and excitement that the beach brings", while highlighting efforts to keep beaches accessible and welcoming for all people “regardless of race, socioeconomic background, ability or gender identity”.

"Surfing is an amazing gift and the beach is an incredible place that should be healthy, safe and accessible to all people," the Surfrider Foundation said.

"As surfers and beachgoers alike, it is our responsibility to foster a vibrant, inclusive community that comes together to protect and enjoy this extraordinary resource."

Over 200 events are expected to be held across the weekend to mark the day, with over 30 countries participating.

More than one million people have reportedly participated in International Surfing Day events over the past decade.

The International Surfing Association (ISA) are among major surfing organisations to have marked the day, which comes a month prior to the sport’s Olympic debut at Tokyo 2020.

"Happy International Surfing Day to all," the ISA said.

"Today we celebrate surfing’s joy, passion, power, community and culture.

"We celebrate the road to Tokyo nearing its destination, as surfing takes the final step to the Olympic stage."

USA Surfing has sought to increase awareness of the sport’s debut at Tokyo 2020, after unveiling murals at San Clemente in California.

The artists produced three murals close to USA Surfing’s headquarters, with local surfers Kolohe Andino and Caroline Marks celebrated ahead of competing at the Olympics.

The World Surf League said highlighted the "solidarity and community" of the day, with the organisation encouraging new and frequent surfers to participate.
