Avarua Harbour is a popular surf spot located in the Cook Islands. It's a place where surfers often gather to ride some waves. The spot features a reef break that's known for its unique setup and varying conditions. It's worth noting that this spot is different from the main harbour at Avatiu, so make sure you’re heading to the right place!

At Avarua Harbour, the optimal swell direction is from the North, with good waves coming in from both the Northwest and Northeast. It's capable of handling swell sizes around 4 feet (about 1.2 meters). The waves generally break over live coral, providing a solid foundation for surfing. Surfers can expect mostly left waves, which can create some fun rides especially when the conditions are right. For the best experience, it's recommended to surf on mid to high tide, with South winds being preferable. This spot is better suited for intermediate surfers due to the reef and the sometimes challenging conditions.

While Avarua Harbour can produce some decent swells, it's important to keep an eye on the wind. When the winds come from the Northeast, they can put a damper on the quality of the waves, making it less enjoyable for surfing. So, it’s a good idea to check the forecast before you head out. Overall, it’s a spot that offers some fun but can vary quite a bit, so be prepared for anything!
