Sissano Lagoon is located on the northern coast of Papua New Guinea. It features a coastal plain that widens to the east, creating a unique surf environment. The area around the lagoon includes swamps, and you can find sandbanks forming off the rivermouth, which can provide some waves for those willing to explore. The local scene is laid back, attracting surfers looking for something a bit different.

The surf at Sissano Lagoon is best with a north-west swell, although it can handle swells coming from the north-east as well. The waves generally break over sand, producing both left and right-handers. It's a spot that works with swell sizes from about 1ft (0.3m) and can be surfed at low, mid, or high tide. The beachbreaks can be a bit tricky at times, with rips in the water, which is something to keep an eye on. It’s mostly suitable for beginners, making it a good option for those just starting out or looking to practice in a less crowded area. For the best conditions, a south-west wind is preferable.

Aside from surfing, the region is known for its natural beauty, and the lagoon itself is a great spot for wildlife watching. Keep your eyes peeled for local fauna, especially around the rivermouth area. Overall, Sissano Lagoon offers a decent surf experience, but it may not be for everyone, especially if you’re after more consistent waves.
