Black Rock (Socials)

Nikao, Rarotonga, Cook Islands
🪸Sharp reef🌀Strong rips

Black Rock (locally known as Socials) is Rarotonga's most popular surf break, located in front of the Nikao Social Centre on the northwest coast. A reef break offering both lefts and rights, it catches North Pacific swells during the November-March season. More accessible than the south coast passes, it's the go-to break for the local surf community.
