In 2004, Surfrider Foundation established the International Surfing Day (ISD) which is held annually on the third Saturday of June. ISD is an environmentally conscious sports-centered holiday that celebrates the love of surfing and to help raise awareness of the world’s beaches and coastal environments.

Now in its 15th year, ISD is celebrated globally with more than 200 events taking place worldwide. In 2018, Mavericks and Volcom teamed up to host the first officially recognized ISD event in Hong Kong. Taking place at Pui O Beach with the theme “Protect & Enjoy”, ISD in Hong Kong featured a range of activities including live music, movie screenings and of course, surfing.

For ISD 2018, HKwalls collaborated with Mavericks and Volcom to create a special mural for the event. Taka, a Hong Kong based Japanese artist, was invited by HKwalls to paint on an improvised wall made of discarded surfboards. Taka’s mural is inspired by the energetic motion of the ocean and depicts a whale leaping out among the green and blue ocean waves.

2004年，衝浪手基金會設立了國際衝浪日（ISD），在每年六月的第三個星期六舉行。 國際衝浪日是一個以體育為中心及具備環保意識的活動，旨在推廣對衝浪的熱愛，並幫助提高人們對世界海灘和海岸環境的認識。

國際衝浪日現已迎來第 15 個年頭，在全球舉辦了超過 200 多場活動。在 2018 年，Mavericks 和 Volcom 聯手在香港舉辦了首屆獲得官方認可的 ISD 賽事。 以「保護與享受」為主題，在貝澳海灘舉辦一系列活動，包括現場音樂、電影放映 — 還有衝浪。

在 ISD 2018 中，HKwalls 與 Mavericks 及 Volcom 合作，為活動創作了一幅特別的壁畫。 居港日本藝術家 Taka 受 HKwalls 邀請，在用廢棄衝浪板搭建的臨時牆面上作畫。 Taka 的靈感來自海洋的動感，描繪了一條鯨魚在藍綠色的海浪中躍出水面。
